If the file cannot be found, the exception is caught in the catch-block. In this example, the error handler simply prints the stack trace, which provides useful information for debugging. In some situations, you may need to perform some clean-up operations, or open another file instead.
If a catch block defines an exception variable, you can use it to obtain more information about the type of exception that occurred. Exceptions can be explicitly generated by a program by using the throw keyword. Exception objects contain detailed information about the error, such as the state of the call stack and a text description of the error. Code in a finally block is executed even if an exception is thrown.
