can anybody explain me about throw and throws keywords. i know that throw is used for throwing the exception manually and throws for indicating the user for indicating that so and so method may are maynot throw the exception. otherthan that is there anything more.
More of a beginner's question, as was your other posting. Please always use titles for your posts which tell what they are about; "exceptions" is a bit too general.
If you ever get your hands on a copy of "Object-Oriented Software Constructrion" by Bertrand Meyer, it has a nice chapter about errors and Exceptions in, although his handling examples are not quite as good as the rest of the chapter. I am forever sending people to the Java Tutorials; there is always something useful there.
