If my opinion below is wrong, I wish to point out that I will improve it. Throw: (Approach to object) throws an exception, which can be either system-defined or self-defined. Here are two examples: throws a system exception

Assume that a division method div () is defined. For Division, exceptions may occur and exceptions may not occur. For this method, it is best to use the throws keyword for declaration. Once an exception occurs, it is handed over to the call center for processing. Because the div () method uses the throws keyword declaration. Therefore, you must handle exceptions when calling this method. [Java] class Math {

I suddenly found that today's poetry is booming, and it seems that I have to write something again. Throw and throws are really not unfamiliar to Java programmers. But as soon as contestants like me mention their differences and connections, they will be covered... For the sake of the future, study it today ~~ If there are any deficiencies, please criticize and correct them... 1) throws The
