I am using Netbeans to develop a simple Java Swing app. It is to load in a text file, then run calculation based on the numbers found in the text file. The main Swing class holds the JFrames and JPanels. I have the file loading code as a separate class file. It returns the number of lines read java error message and a List of numbers back to the main Swing app. I realised that if the file reading fails (i.e. try -> catch (Exception ex)), the entire app will crash. What's the best way to handle errors resulting from my scenario above? That is to say, the file loading code crashes and I don't want the entire program to crash. I want the program to say the file is corrupted and wait for user to load new file. Any thoughts?

If there is a corruption, then rather than throwing an exception, set a boolean flag and loop as long as the flag is set. That way, when a g
