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();
      }
}
