What is the output for the below code?

import java.io.FileNotFoundException;
class A{
      public void printName() throws FileNotFoundException{
            System.out.println("Value-A");
      }
}
class B extends A{
      public void printName() throws NullPointerException{
            System.out.println("Name-B");
      }
}
public class Test{
      public static void main (String[] args) throws Exception{
            A a = new B();
            a.printName();
      }
}

A. Value-A

B. Compilation fails-Exception NullPointerException is not compatible with throws clause in A.printName()

C. Name-B

D. Compilation succeed but no output

E. None of these

Answer: Option C

Solution(By Examveda Team)

The overriding method can throw any unchecked (runtime) exception, regardless of exception thrown by overridden method. NullPointerException is RuntimeException so compiler will not complain.
