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();
}
}
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.
