throw
A Java(TM) programming language keyword that allows the user to throw an exception or any class that implements the "throwable" interface. A throw statement is used to cause an exception to be thrown. The expression in a throw statement must produce a reference to an object that is an instance of the Throwable class or one of its subclasses. Otherwise, the compiler issues an error message. You typically want the expression in a throw statement to produce an object that is an instance of a subclass of the Exception class.
Here is an example of a throw statement:
throw new ProtocolException();
throws
A Java(TM) programming language keyword used in method declarations that specify which exceptions are not handled within the method but rather passed to the next higher level of the program.
