Working Code

Try this:

public class TestExceptions extends Exception {
    public TestExceptions( String s ) {

    public static void main(String[] args) throws TestExceptions{
        try {
            throw new TestExceptions("If you see me, exceptions work!");
        catch( Exception a ) {
            System.out.println("Working Status: " + a.getMessage() );


There are a number of issues with the code you posted, including:

  • Catching Error instead of Exception
  • Using a static method to construct the exception
  • Not extending Exception for your exception
  • Not calling the superclass constructor of Exception with the message

The posted code resolves those issues and displays what you were expecting.
