throws used in a method declaration etc, to declare the possible exceptions that can be thrown by the method.
void method() throws Exception {
}

throw used to actually do the throwing
try{
...
...
} catch (NumberFormatException nfEx){
throw new CustomNumberFormatException();
} catch (CustomNumberFormatException){
}

throw and throws are very important parts of Java's Exception Handling functionality.
To get the best bang for your buck, I'd suggest checking out this Sun Tutorial: Lesson: Handling Errors with Exceptions
