Chapter: Java Basics Last Updated: 19-06-2016 18:03:21 UTC

Program:

            /* ............... START ............... */
                
interface IntExample {
	public void sayHello();
}

public class JavaInterfaceExample implements IntExample {

	public void sayHello() {
		System.out.println("Hello Welcome !");
	}

	public static void main(String args[]) {
		JavaInterfaceExample javaInterfaceExample = new JavaInterfaceExample();
		javaInterfaceExample.sayHello();
	}
}
                /* ............... END ............... */
        

Output

Hello Welcome !

Notes:

  • Interface looks like class but it is not a class.
  • An interface can have methods and variables just like the class but the methods declared in interface are by default abstract (only method signature, no body).
