We don't: it violates encapsulation.
It is
fine to say, "No, I don't want my own behavior - I want my parent's behavior"
because it's assumed that you'll only do so when it maintains your own state
correctly.
However,
you can't bypass your parent's behavior - that would stop it from enforcing its
own consistency. If the parent class wants to allow you to call the grandparent
method directly, it can expose that via a separate method... but that's up to
the parent class.
Workaround
using flag:
package com.java.oops;
/**
* Grand Parent Class
*/
class AClass {
public void
method(boolean gpFlag) {
System.out.println("Class A");
}
}
/**
* Parent Class.
*/
class BClass extends AClass {
public void
method(boolean gpFlag) {
super.method(gpFlag);
if(gpFlag) {
return;
}
System.out.println("Class B");
}
}
/**
* Child Class.
*/
class CClass extends BClass {
public void
method(boolean gpFlag) {
super.method(gpFlag);
System.out.println("Class C");
}
}
public class CallGrandParent {
public static void main(String[] args) {
CClass c = new CClass();
boolean gpFlag = true;
c.method(gpFlag);
}
}
Output:
Class A
Class C
