Are try blocks ONLY used for connections? I've seen it used in a java program before for the same exact reason.
Are try blocks ONLY used for connections? I've seen it used in a java program before for the same exact reason but never for anything else. How does it know what it is looking for that works or fails if it is not only for connections?

they are used any time you are worried that a function you are calling might produce an error. Where as a standard error will typically break your program. If you use a try/catch then you can catch the error and handle it gracefully to allow your program to continue in a different manner or let your user know what the error is and why the program is stopping.
