Question
What is the output of the following Java program?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"); } }}
Solution
The output of the Java program will be: "Caught base class exception"
In Java, the catch blocks are examined in the order they appear. The first catch block that is capable of handling the exception is the one that gets executed. In this case, since the Derived class extends the Base class, the catch block for Base is capable of handling the exception of type Derived. Therefore, the catch block for Base is the one that gets executed, and "Caught base class exception" is printed to the console. The catch block for Derived is never reached.
