Yes, an interface can if it has a class in it.

Here is the code what i am trying to say...

// MethodImplementedInterface.java
/**
*@author Arpan Mondal(www.arpanmondal.tk)
*/

interface A {
public class B {
B() {
display();
}
public void display() {
System.out.println("This is the
method in the interface.");
}
}
}

class C implements A {
B objB = new B();
void display() {
System.out.println("This is the method in
the class.");
}
}
public class MethodImplementedInterface {
public static void main(String[] args) {
C objC = new C();
objC.display();
}

}

The output of the above code is here...

This is the method in the interface.
This is the method in the class.
