Hi
Can any one tell me how to call a subclass method from a superclass?
For example:
I have a class A,B and C. Now B and C extends A.
So is there any way that we can call a method of B in A?
Thanks
Abhishek

In class A:
void myMethod () {
B b = new B();
b.theMethodOfB();
}
This also works when B has overridden a method from A.
See http://docs.oracle.com/javase/tutorial/java/IandI/override.html for more info

Well depending on whether or not the extending classes are static or non-static-the same applies for your methods within these classes-there are many different ways to access them. Here is a sample i made to try help you:
public class X {
public static void main(String[] args) {
Y.methodY1();//calling static method from a static class Y methodY1()
Y classB = new Y();
classB.methodY2();//calling a non-static method from static class Y methodY2()
// new Y().methodY2();//another way to call methodY2-just an extension of the above
X classA = new X();
classA.new Z().methodZ1();//calling a non-static method from non-static class Z methodZ1()
//new X().new Z().methodZ1();//another way to call methodZ1 -just an extension of the above
}
static class Y {
private static void methodY1() {
}
private void methodY2() {
}
}
class Z {
private void methodZ1() {
}
}
}

possible? off course.
but ... a bit fishy.
this would imply that A knows the type (whether) or not it inherits A or not.
but why exactly do you need something like this? sometimes knowing the reason why doing something makes it a lot easier to respond, and it might help us give the correct answer you are looking for.
heres also a good link to look at if your extending classes are in different files and not the same class as i illustrated in my previous post:http://docs.oracle.com/javase/tutorial/java/IandI/subclasses.html and this:http://www.javacoffeebreak.com/java104/java104.html
