    Java is a programming language (♦ see DEF) multiplatform and object oriented, created in 1995. The Oracle company owns the Java technology, after having bought it from Sun Microsystems.

    Java allows you to create, among other things, Web App. and websites, software and games .

    Code Examples

    → Let's start with very simple codes. The more you progress, page after page, the more sophisticated the scripts will be. However, you must go over 30 to 40 pages per level, before moving on to the next step...

    → In order to evaluate your codes, click on the icon on the left at the bottom of the page (gears), then choose a compiler from the list that will be open in another tab. Finally, test your work.

    NOW REPRODUCE AND IMMERSE YOURSELF!

    C 0001 - Hello World !

    Reproduce this code (please do not copy-paste!). Watch out for the indentation !
    public class Main {
      public static void main(String[] args) {
        System.out.println("Hello World !");
      }
    }
    

    C 0002 - Variables

    Reproduce this code (please do not copy-paste!). Watch out for the indentation !
    public class Main {
      public static void main(String[] args) {
        String name = "John";
        System.out.println(name);
      }
    }
    

    C 0003 - Types of informations

    Reproduce this code (please do not copy-paste!). Watch out for the indentation !
    public class Main {
      public static void main(String[] args) {
        int myNum = 10;               // Integer
        float myFloatNum = 3.99f;    // Floating point
        char myLetter = 'F';         // Character
        boolean myBool = true;       // Boolean
        String myText = "Bonjour tout le monde !";     // String
        System.out.println(myNum);
        System.out.println(myFloatNum);
        System.out.println(myLetter);
        System.out.println(myBool);
        System.out.println(myText);
      }
    }
    

    C 0004 - Declarations and Statements

    Reproduce this code (please do not copy-paste!). Watch out for the indentation !
    public class Main {
      public static void main(String[] args) {
        int x = 60;
        int y = 28;
        if (x > y) {
          System.out.println("x is bigger than y");
        }  
      }
    }

    CHOOSE YOUR COMPILER

    Reproduce this code, choosing one of the compilers below (♦ see DEF) (don't copy-paste! It would be too easy). They have the same function, just pick up one according to your preferences.

    When you copy your code, replace the existing code (by default) with your own.

    Warning ! For some of these compilers, you might have to choose the programming language yourself, in a specific menu which is offered to you. Of course, don't forget to click on RUN !
