overriding

[srinivas sridaragaddi]

 class A{
void m1(A a){System.out.println("A");
}
}
 
class B extends A{
void m1(B b){System.out.println("B");
}
}
class C extends B{
void m1(C c){System.out.println("C");
}
}
class E{
public static void main(String args[]){
A a1=new A();
B b1=new B();
C c1=new C();
A c2=new C();
c2.m1(a1);
c2.m1(b1);
c2.m1(c1);
}
}
   

options:


prints:AAA
prints:ABC
prints:CCC
compile time error
run time error




output:AAA
but i was expecting it be CCC

The method m1 in class B does not override the method m1 in class A, and the method m1 in class C does not override the method m1 in classes A and / or B.

Because the types of the arguments are different in the three m1 methods, these are not overridden methods, so method call polymorphism does not apply here.
