Suppose I have a controller that loads a file and hands it over to the processing. Should I handle the exception in the file loader and return Null if something is wrong, or should I throw the exception and handle it in the controller? Without the file the rest of the program cant work. Where should I handle a exception that shuts down the program properly?I want to shut down an Android application properly.
Where should I handle fatal exceptions
exceptions;exception handling
In layman's words:You should not return null. The exception should be handled in the top-most layer.The program should not terminate, but give feedback to the user, unless it is a Unix style command line program where it's ok to terminate after showing an error message.By definition no exception is fatal and each one can be handled. Errors are fatal and cannot be recovered from.Exceptions and errors are not the same.
