Final Answer


When you use a try-catch block, you're essentially telling the compiler that you're going to take care of displaying the error messages--no built-in messages will show. Instead, whatever error prompts you include in the catch statements will show.

When I run your program, I see your error messages, but no built-in Java error messages; this is how it should be. Really, the errors are being thrown--but you're catching them, so Java doesn't display the default message on the console.
