interface example program in java

Definitions

Interface : It's used to hide the implementation of the object from it's class. Interface provides a mechanism to achieve the multiple Inheritance in java. Java does not support multiple inheritance using interface we can achieve this goal in Java Programming Language.

Example Program :

interface myInt

{

   void In1();

   void In2();

}

class toInt implements myInt

{

  public void In1()

  {

     System.out.println("Welcome to In1 !!");

  }

  public void In2()

  {

     System.out.println("Interface 2 is Launched !!!!");

  }

  public static void main(String args[])

  {

     myInt obj = new toInt();

     obj.In1();

     obj.In2();

  }

}

Sava this file : toInt.java

Compile this file : javac toInt.java

Run this file : java toInt

Output : 

Welcome to In1 !!

Interface 2 is Launched !!!!
