calling overridden superclass method

[meenakshi ashokkumar]

if i have a class A with display method,
class B extends A with display method &
class C extends B with display method,
how can i call the display meethod in class A thro' a reference variable that refers to a C object?

well, you can't directly.
but the following code would work,

class A {
public void display() {
System.out.println("A.display");
}
}
class B extends A {
public void display() {
System.out.println("B.display");
}
public void superDisplay() {
super.display();
}
}
class C extends B {
public void display() {
System.out.println("C.display");
}
}
class Test {
public static void main(String[] args) {
C c = new C();
c.display(); // calls C's display() method
c.superDisplay(); // calls A's display() method ultimately
}
}

The issue here is, we can't directly call c.super.super.display() you know...so we have to go via delegation model...
