Q. Determine output:
class A{
public void printName(){
System.out.println("Name-A");
}
}
class B extends A{
public void printName(){
System.out.println("Name-B");
}
}
class C extends A{
public void printName(){
System.out.println("Name-C");
}
}
public class Test{
public static void main (String[] args){
B b = new B();
C c = new C();
b = c;
newPrint(b);
}
public static void newPrint(A a){
a.printName();
}
}
✅ Correct Answer: (C)
Compilation fails due to an error on lines 5
Explanation: Reference variable can refer to any object of the same type as the declared reference OR can refer to any subtype of the declared type. Reference variable "b" is type of class B and reference variable "c" is a type of class C. So Compilation fails.
