Declaring and handling exceptions:
If the code within a method may throw a checked exception, then you must do one of two things:
- declare in the method header that an exception may be thrown - in this case you do not handle the exception within the method, but simply pass it on;
- catch the exception and deal with it within the method, using a try-catch statement.
The keyword throws advertises that the method is capable of throwing an exception. In any code that uses this method some action will need to be taken to cater for this exception.
