Java Programming - Exceptions - Discussion

5. 

What will be the output of the program?

public class RTExcept 
{
    public static void throwit () 
    {
        System.out.print("throwit ");
        throw new RuntimeException();
    }
    public static void main(String [] args) 
    {
        try 
        {
            System.out.print("hello ");
            throwit();
        }
        catch (Exception re ) 
        {
            System.out.print("caught ");
        }
        finally 
        {
            System.out.print("finally ");
        }
        System.out.println("after ");
    }
}

[A]. hello throwit caught
[B]. Compilation fails
[C]. hello throwit RuntimeException caught after
[D]. hello throwit caught finally after

Answer: Option D

Explanation:

The main() method properly catches and handles the RuntimeException in the catch block, finally runs (as it always does), and then the code returns to normal.

A, B and C are incorrect based on the program logic described above. Remember that properly handled exceptions do not cause the program to stop executing.

Since RuntimeException is not a subclass of Exception class and neither it needs to be declared or handle then how can a catch clause with Exception object as argument can handle this Runtime Exception?

Sorry, but RuntimeException class is the Parent class of Exception class. So it can be handled by exception class.

Hi, Exception class is parent class of RunTimeException.

I have a question on above code. I think the static method need to be execute first.

If we have normal static method and public static void main() method, First preference is given to static main method.

Why we do not need to statement 'throws' RuntTimeEx?

Class is the Parent class of Exception class.
