class Base extends Exception {}
class Derived extends Base {}
public class Main {
public static void main(String args[]) {
// some other stuff
try {
// Some monitored code
throw new Derived();
}
catch(Base b) {
System.out.println("Caught base class exception");
}
catch(Derived d) {
System.out.println("Caught derived class exception");
}
}
} |
(A) Caught base class exception
(B) Caught derived class exception
(C) Compiler Error because derived is not throwable
(D) Compiler Error because base class exception is caught before derived class
Answer: (D)
Explanation: See Catching base and derived classes as exceptions
Following is the error in below program
Main.java:12: error: exception Derived has already been caught
catch(Derived d) { System.out.println("Caught derived class exception"); }
