The basics of Java.

-----------------------------
Java IDE

First thing's first, you need to set up an IDE. I'll let Wikipedia explain what an IDE is if you've never come across the term.

An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development

http://en.wikipedia.org/wiki/Integra...nt_environment

Here is a list of Java IDEs:

• Eclipse
• Netbeans
• BlueJ
• IntelliJ IDEA

For the purpose of this tutorial, we will be using BlueJ. BlueJ is a fantastic IDE for new Java programmers, it can tell you where things go wrong which is always a plus.

Here's the direct download link - http://www.bluej.org/download/download.html

-----------------------------
Tutorial Notation

Mutator - A mutator is designed to modify existing fields, see type VOID.

public void editAge() 

Accessors - Accessors are used to return, display or call values from fields, types include boolean, String, int, double and more - These are data types!

public String getName() 

Parameters - Parameters are passed through the method, they're added inside of the brackets. See code below.

public void editAge(int age) 

What this does is, when the editAge method is called you will be prompted to add an age.

Constructor - Say your class is called Tutorial, here's the constructor.

public class Tutorial
{
  // The constructor is below 
  public Tutorial()
  {

  }
  //End constructor
} 

So there's the notation.

-----------------------------
Your first script - Your information. AFTER EACH STEP, COMPILE (press Compile button).

Hopefully you're now eager to write your first small script, and so we shall.

1. On your BlueJ document, click New Class and set the Class Name to Me. Once it's created you'll see a small yellow box on your window, double click it and delete everything in there. It's all nonsense.

2. So you should have a blank document, we need to declare our class and constructor. Here's our code.

public class Me
{
   public Me()
} 

3. At present our script does nothing, so let's create some field declarations. Here's a brief overview of what we want our script to hold:

• First Name
• Surname
• Age
• School
• Year

So, we've got our list, it's probably best we assign relevant data types to our fields.

String - Text that can include numbers e.g. 22 Carb Street.
int - Whole numbers only, also supports a limited range.
double - Whole and decimal numbers e.g. £2.50 (minus the £).
boolean - Returns true or false, nothing else.

In order to declare our fields, we merely add private 'datatype' 'fieldname';
For example, First Name would be private String firstName; - I've named it firstName for ease, it can be anything.

It is imperative you remember the semi-colon at the end of the lines, bar the method title.

public class Me
{
   private String firstName;

   public Me()
  {

  }
} 

Add all of your fields, try not to peak at mine, you're here to learn.

Show Hide

public class Me
{
   private String firstName;
   private String surname;
   private int age;
   private String school;
   private int year;

   public Me()
  {

  }
} 

4. Now we need to add data to those fields using parameters, remember those?
Declare appropriate parameters in your constructor. You can call your parameter variables anything and you must assign them a datatype.

...
public Me(String myName, String lastName, int myAge, String mySchool, int myYear)
{

}
.. 

5. Next, we assign our parameters to our private fields. We simply do that by adding..

firstName = myName 

Match your private fields with your parameter values. Your whole code should look like this:

public class Me
{
   private String firstName;
   private String surname;
   private int age;
   private String school;
   private int year;

   public Me(String myName, String lastName, int myAge, String mySchool, int myYear)
  {
      firstName = myName;
      surname = lastName;
      age = myAge;
      school = mySchool;
      year = myYear;
  }
} 

What does the above do? - Good question, assuming you've compiled your code. Go onto BlueJ, right click and then click new Me(String myName, String lastName...)

Once that has appeared, you're prompted to enter values for your parameters. Where you have to enter a String you must wrap it in speech marks, so beside String myName you must put "Tuts" instead of Tuts.

6. Writing Methods (I've put it in bold because Methods are cool)

INCREMEN
Say it's your birthday tomorrow, and in our script your age is 20, you'll want to update it to 21 right? Let's right a method for that. What we want to do is increment (add) 1 to the age every time the method is called.

public void oneYear()
    {
      age = age + 1;
    } 

Here's how it works, we're using our mutator because we're changing data or existing fields.
The age = age + 1 simply grabs what's currently inside the age variable and adds 1 to it.
(Note: Remember we set age = myAge in our constructor?). Similarly you could use the shorthand form

age += 1; 

RETURN AGE
You'll want to see if your age has changed right? Let's create another method. This time we're using accessors because we're not changing fields.

    public int getAge()
    {
        return age;
    } 

You're merely returning what's in the age variable, simples.

So now your code should be similar to this:

public class Me
{
   private String firstName;
   private String surname;
   private int age;
   private String school;
   private int year;

   public Me(String myName, String lastName, int myAge, String mySchool, int myYear)
  {
      firstName = myName;
      surname = lastName;
      age = myAge;
      school = mySchool;
      year = myYear;
  }
  
    public void oneYear()
    {
      age = age + 1;
    }
    
    public int getAge()
    {
        return age;
    }
} 

Let's print all of this out in the format of text.
Declare a mutator called getInformation.

Inside your mutator add:

System.out.println("Hello my name is " + firstName + " " + surname + ". I am " + age + " years old. I attend " + school + " and I'm in year " + year); 

Your document should look like this:

public class Me
{
   private String firstName;
   private String surname;
   private int age;
   private String school;
   private int year;

   public Me(String myName, String lastName, int myAge, String mySchool, int myYear)
  {
      firstName = myName;
      surname = lastName;
      age = myAge;
      school = mySchool;
      year = myYear;
  }
  
    public void oneYear()
    {
      age = age + 1;
    }
    
    public int getAge()
    {
        return age;
    }
    
    public void getInformation()
    {
        System.out.println("Hello my name is " + firstName + " " + surname + ". I am " + age + " years old. I attend " + school + " and I'm in year " + year);
    }
} 

In order to run it, through BlueJ, compile it, right click and then do new Me(String myName, String lastName...)

Input your relevant information, you should see a red box appear at the bottom, right click it and you'll see your three (or more if you wrote your own) methods int getAge(), int oneYear(), void getInformation().

Sorry for any vagueness, grammatical errors and what not. I've got work in a minute so I tried to get through it quickly. It took me 50 minutes to write out such a small tutorial. When I return I'll go through ArrayLists, Arrays and we will implement a text based interface for our small script we've just written.

Thread moved by Chris (Forum Super Moderator): From "Designing & Development". Great guide, thanks for posting!

This is brilliant +rep for the guide.

Thanks GoldenMarc!

-----------------------------
Let's set up our Command Line Interface

Here's Wikipedia's definition of a CLI

A command-line interface (CLI) is an interface or dialog between the user and a program, or between two programs, where a line of text (a command line) is passed between the two.

In Java we use things called API's or libraries, when the library is implemented into our Java document, we can call methods within the library. For this, we're using Scanner. Here's the API http://docs.oracle.com/javase/1.5.0/...l/Scanner.html

To import this into our document, we simply declare

import java.util.Scanner 

The java.util package contains classes that deal with collections, events, date and time, internationalization and various helpful utilities.

http://java.about.com/od/javautil/java_util.htm

Say we want to import a number of APIs within java.util, for example
[PHP]import java.util.Scanner;
import java.util.HashMap;
import java.util.???;[PHP]

We can simply write

import java.util.*; 

With the latter code, it will look at ALL of the API's within the java.util. So for ease, we're going to use .*

Now, I'm going to introduce you to a new method declaration which looks like this

public static void main(String[] args)
{

} 

This is our main method, and does not need objects (those red boxes on BlueJ).

For this project we will be using the same Me project in the first post.

1. Start your document.

public class Me
{
    public static void main(String[] args)
    {
        
    }
} 

We don't need a constructor for our project, it's not really important IMO.

2. Import out Java library - This goes before our 'public class Me', simply add

import java.util.Scanner; 

or

import java.util.*; 

3. We need to set up our Scanner, in order to do that we have to call a Scanner object, so in order to do that we add this code within our public static void main(String[] args)

Scanner scan = new Scanner(System.in); 

System.out in Java will print out, so System.in will read in, we've declared a Scanner called scan which reads inputs.

4. Let's set up a menu, in our Me project we had to make an object to input information for firstName, surname, age, school, year. For our CLI, we have to write some manual code.

Please note: When using System.out.println("hi") (which outputs hi), we use \n within the speech marks to declare a new line. For example

System.out.println("Hello Habbox \n This is my Java Tutorial \n I hope it's good"); 

Will output:
Hello Habbox
This is my Java Tutorial
I hope it's good

5. Setting up a menu, we use our System.out.println() method which outputs to the terminal.

import java.util.*;

public class Me
{
    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        
        System.out.println("What would you like to do?");
    }
} 

When run, it'll look like this:


Now we'll implement a numeric menu which will be used to read changes.

Add

System.out.println("1. Add first name");
System.out.println("2. Add surname");
System.out.println("3. Add age");
System.out.println("4. Add school");
System.out.println("5. Add school year"); 

or, for shorthand you could add

System.out.println("1. Add first name \n 2. Add surname \n 3. Add age \n 4. Add school \n 5. Add school year"); 

6. IF statement & Java operators - MUST LEARN.

Now we welcome If statements, here's how an if statment is set out.

If(This) {
Then do this } ELSE {
Do this
} 

So here's a simple If statement, we'll assign the variable Age 3.

If(Age == 3) {
System.out.println("Yes, the age is 3");
} else {
System.out.println("No the age isn't 3");
} 

Multiple If statements.

If(Age == 3) {
System.out.println("Yes the age is 3");
} else if(Age == 4) {
System.out.println("Yes the age is 4");
} else if (Age == 5) {
System.out.println("Yes the age is 5");
} else {
System.out.println("That is not the age");
} 

Java operators: IMPORTANT.

Age = 3 - This does NOT mean equal, this means store the value 3 in the variable Age.
Age == 3 - This does mean equal, this says Age is equal to 3, we only use == for numbers, not Strings.
> - More than.
< - Less than.
!= - Does not equal.
|| - Or.
&& - And.

Similar to PHP and other languages.

7. Reading the choice.
In our Scanner API there is a method called nextInt (just as well as nextLine() for String, nextLong() for Long and more). So we're going to be using nextInt() because our menu is numeric "1. Add first name" - We want the user to put 1 if they want to add a first name.

So just underneath our Scanner declaration add

int choice; 

and then, underneath our menu add

choice = scan.nextInt() 

What happens now is that our Scanner called scan will read the next integer put in from the keyboard and it'll store the input into the integer choice.

Something else I've forgot, we want another choice in the menu to Exit, go back and edit your document to hold a 6th option, quit.

OK, so now, we've got our choice. Let's set up some if statements.

8. Determine what to do with each choice.

if(choice == 1)
{
  // Do something that relates to choice 1; firstname.
} else if(choice == 2) {
  // Do something that relates to choice 2; surname.
} else if(choice == 3) {
 // Do something that relates to choice 3; age.
} else if(choice == 4) {
 // Do something that relates to choice 4; school.
} else if(choice == 5) {
 // Do something that relates to choice 5; year.
} 

Now, we've forgot our 6th step; quit.

We need to wrap our if statement in a loop.
Loops will continue to be executed until the condition is not met.

int i = 0;
        while(i < 5)
        {
            System.out.println("hi");
            i = i+1; // or i++;
        } 

OK so we've declared integer i to equal 0, the code says that WHILE I is less than 5, print out "hi" and then add 1 to i. So on the first run, i = 0. Then after the first loop adds 1 to i, i = 1. It happens until i is not less than 5 anymore. It should print out hi 4 times.

We need this while loop, however our condition isn't the same, we need to say, well, while the choice does not equal 6 (which is exit) perform this code

while(choice != 6)
{
 // Input our long IF statement(s).
} 

There we go, that's our While loop.

Your code should now look similar to this;

import java.util.*;

public class Me
{
    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        int choice;
        
        System.out.println("What would you like to do?");
        System.out.println("1. Add first name");
        System.out.println("2. Add surname");
        System.out.println("3. Add age");
        System.out.println("4. Add school");
        System.out.println("5. Add school year");
        System.out.println("6. Quit");
        
        choice = scan.nextInt();
        
        while(choice != 6)
        {
            if(choice == 1)
            {
                
            } else if(choice == 2) {
                
            } else if(choice == 3) {
                
            } else if(choice == 4) {
                
            } else if(choice == 5) {
                
            }
        }
        
        
    }
} 

9. Adding our fields.

Just like in our first project, we had firstName, surname, age, school, year. We need to declare those again within our new program. It's similar to before. Here's my declarations.

Scanner scan = new Scanner(System.in);
        int choice;
        //Start new declarations.
        String firstName;
        String surname;
        int age;
        String school;
        int year; 

Note: For shorthand you could have,

int choice, age, year;
String firstName, surname, school; 

10. Let's write some methods.

Add name

if (choice == 1) {
 // Implement this method below.
} 

So we want to add a name (first name), let's have the CLI ask us what our name is.
[PHP]if (choice == 1) {
System.out.println("What is your name? \n");
}

Now we want to read that input, because name is String we want to use the method nextLine(); (See API method list for more information).

if (choice == 1) {
System.out.println("What is your name? \n");
firstName = scan.nextLine();
} 

We could add a confirmation output if we want.
[PHP]if (choice == 1) {
System.out.println("What is your name? \n");
firstName = scan.nextLine();
System.out.println("I knew it was you " + firstName);
}[PHP]

Our output will look like this:
What is your name?
Dan (my input)
I knew it was you Dan

Add surname

We can duplicate our Add first name code and edit the variables

} else if (choice == 2) {
 System.out.println("What is your surname? \n");
 surname = scan.nextLine();
} 

Add age

} else if (choice == 3) {
 System.out.println("How old are you? \n");
 age = scan.nextInt();
 System.out.println("I was " + age + " years old when I was your age");
} 

I will let you add School and Year - It is similar to the already stated methods.

So right now your program should be similar to this

import java.util.*;

public class Me
{
    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        int choice;
        String firstName;
        String surname;
        int age;
        String school;
        int year;
        
        System.out.println("What would you like to do?");
        System.out.println("1. Add first name");
        System.out.println("2. Add surname");
        System.out.println("3. Add age");
        System.out.println("4. Add school");
        System.out.println("5. Add school year");
        System.out.println("6. Quit");
        
        choice = scan.nextInt();
        
        while(choice != 6)
        {
            if(choice == 1)
            {
                System.out.println("What is your name?");
                firstName = scan.nextLine();
                System.out.println("I knew it was you " + firstName);
               
            } else if(choice == 2) {
                System.out.println("What is your surname?");
                surname = scan.nextLine();
            } else if(choice == 3) {
                System.out.println("How old are you?");
                age = scan.nextInt();
                System.out.println("I was " + age + " years old when I was your age");
            } else if(choice == 4) {
                System.out.println("What school do you attend?");
                school = scan.nextLine();
            } else if(choice == 5) {
                System.out.println("What year are you in?");
                year = scan.nextInt();
            }
        }
       
        
        
    }
} 

However, when it's run and the first method is called (one to add your first name) you will notice that you're not given the chance to input anything as it'll print "What is your name" and then print "I knew it was you .." straight after.

The only way I've found around it is implementing another scan.nextLine() which will read your enter key.

if(choice == 1)
            {
                System.out.println("What is your name?");
                enter = scan.nextLine();
                firstName = scan.nextLine();
                System.out.println("I knew it was you " + firstName);
               
            } 

This should be used after every print that requires an input, implement it into all of your methods.

We also need to include the menu and choice reading in every method we're using, for every choice.
We can copy and paste

System.out.println("What would you like to do?");
        System.out.println("1. Add first name");
        System.out.println("2. Add surname");
        System.out.println("3. Add age");
        System.out.println("4. Add school");
        System.out.println("5. Add school year");
        System.out.println("6. Quit");
        
        choice = scan.nextInt(); 

Into all of our methods too.

Your code should now look like this:

import java.util.*;

public class Me
{
    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        int choice;
        String firstName;
        String surname;
        int age;
        String school;
        int year;
        String enter;
        
            System.out.println("What would you like to do?");
            System.out.println("1. Add first name");
            System.out.println("2. Add surname");
            System.out.println("3. Add age");
            System.out.println("4. Add school");
            System.out.println("5. Add school year");
            System.out.println("6. Quit");
        
            choice = scan.nextInt();
        
        
        while(choice != 6)
        {
            if(choice == 1)
            {
                System.out.println("What is your name?");
                enter = scan.nextLine();
                firstName = scan.nextLine();
                
                System.out.println("I knew it was you " + firstName);
                System.out.println("What would you like to do?");
                System.out.println("1. Add first name");
                System.out.println("2. Add surname");
                System.out.println("3. Add age");
                System.out.println("4. Add school");
                System.out.println("5. Add school year");
                System.out.println("6. Quit");
        
                choice = scan.nextInt();
        
               
            } else if(choice == 2) {
                System.out.println("What is your surname?");
                enter = scan.nextLine();
                surname = scan.nextLine();
                
                System.out.println("What would you like to do?");
                System.out.println("1. Add first name");
                System.out.println("2. Add surname");
                System.out.println("3. Add age");
                System.out.println("4. Add school");
                System.out.println("5. Add school year");
                System.out.println("6. Quit");
        
                choice = scan.nextInt();
        
            } else if(choice == 3) {
                System.out.println("How old are you?");

Outside of our While loop, we want to issue a goodbye message, this will then stop the user from being able to interact further with our project.

BlueJ users, if you can see the colours on your document, outside of the purple box add something like

System.out.println("Thank you for using the program, goodbye"); 

11. AAHHHHHHHHHHHH.

You need to go back and initialize all of your fields. For example:

        String firstName = null;
        String surname = null;
        int age = 0;
        String school = null;
        int year = 0; 

Because we'll be calling on them in our next step, they need a default value even before we edit anything.

12. My Information

This method is entirely up to you to complete.

Edit the existing code so that we can introduce a choice called My Information which is displayed before Quit.

So it'll be
..
6. My Information
7. Quit

You must edit the menu and the while loop.

Once you've edited all of that, we'll print out all of your details

} else if(choice == 6) {
                System.out.println("Your name is " + firstName + " " + surname + ". You are " + age + " years old. You attend " + school + " and you're in year " + year);
                
                System.out.println("What would you like to do?");
                System.out.println("1. Add first name");
                System.out.println("2. Add surname");
                System.out.println("3. Add age");
                System.out.println("4. Add school");
                System.out.println("5. Add school year");
                System.out.println("6. My information");
                System.out.println("7. Quit");
        
                choice = scan.nextInt();
            } 

We're done!!

133 lines of code, and we're done.

and here's the visual output:


When you press 7 it just says Goodbye and stops any text input.

This is excellent for beginners. I myself have studied Java for three years. You've put a lot of work into this and it shows, even scanning through it looks exceptional, I recommend this to people on here who study low-end languages (html,css,php). Java is a step up, though I prefer C++!

Thanks for the feedback Zak, I'm glad you appreciate it.

[Cornholio!.]

This is great! I'm sure it will help a ton of people! If it hasn't already. ;D

[lawrawrrr]

Oh this is going to be so useful! Only read about half but it's really comprehensive. Great guide for beginners, thank you!! +rep

I myself are making a personal darts application in Java atm

Hey @Zak;, how's your application going? It's been 5 months since I last updated this thread, I'll produce a new and more extensive tutorial regarding GUIs.
