throw is used to send and intentional exception and throws is used when you dont want your function to handle the exception. It is handled by the function which is calling it.

Throw is used to throw user-defined exception. It is written in try-catch block. Throws is used to throw system-defined exception. No Try-catch is required . void mthorw(){ throw new ArithmeticException("sorry"); } void mthrows()throws ArithmeticException{ //method code }

'throws' is a clause that you give to a class or a method which needs to be handled. 'throw' is a keyword that specifies action to throw the necessary exception.

Throw is used whenever we want to raise an exception. Throws is used at function or class level to indicate that this may raise exception during the course of execution and thus jvm handles it.

Difference between throw and throws are: throw is used to actually throw the exception, whereas throws is declarative for the method. They are not interchangeable. Throws: this is to be used when you are not using the try catch statement in your code but you know that this particular class is capable of throwing so and so exception(only checked exceptions). In this you do not use try catch block but write using the throw clause at appropriate point in you code and the exception is thrown to caller of the method and is handled by it. 1)throw is used to explicitly throw an exception. And throws is used to declare an exception. 2)checked exception can not be propagated without throws. And checked exception can be propagated with throws. 3)throw is followed by an instance.And throws is followed by class. 4)throw is used within the method.And throws is used with the method signature. 5)You cannot throw multiple exception And You can declare multiple exception e.g. public void method()throws IOException,SQLException. read less
