在try catch中throw

在try catch中,throw用于手动抛出一个异常。当程序运行过程中发生了某种错误或异常情况,我们可以使用throw关键字主动抛出一个异常,以便在程序的其他地方进行处理。throw语句后面通常跟着一个异常对象,可以是Java内置的异常类,也可以是自定义的异常类。通过throw关键字,我们可以向上一层的调用函数传递异常,直到被catch到并进行相应的处理。这样可以保证程序的健壮性,并且可以根据不同的异常类型进行不同的处理操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
