Question

I have a program and I am catching an error. I need the program to stop and stay idle if there is an exception.

I have this:

// Try to parse the integer just to make sure it's an integer.
try {
    Integer.parseInt(celsiusTxtField.getText());
}

// Catch it if it's not an integer and murder the user for being stupid. They should know temperature consists of numbers and not letters.
catch(NumberFormatException e) {
    JOptionPane.showMessageDialog(null, "You did not submit a number. Please try again.", "General Error - Error #2", JOptionPane.ERROR_MESSAGE);
}

But, even though it shows the error message, it still continues on with the script.

This is probably really simple, but I’m new to Java, so please excuse my not knowing.

Answer 1

I just found a way to do this.

Move everything under TRY, and that way, the CATCH is the last thing, so there’s nothing else to be executed.
