Answer 1

Answer:

Explanation:

interface MyInterface

{

/* compiler will treat them as:

* public abstract void method1();

* public abstract void method2();

*/

public void method1();

public void method2();

}

class Demo implements MyInterface

{

/* This class must have to implement both the abstract methods

* else you will get compilation error

*/

public void method1()

{

System.out.println("implementation of method1");

}

public void method2()

{

System.out.println("implementation of method2");

}

public static void main(String arg[])

{

MyInterface obj = new Demo();

obj.method1();

}

}
