try、catch 和 throw 语句 (了解)

C++ 异常使用 try.catch 和 throw 关键字. 引发表达式指示错误或异常情况. 可以将任何类型的对象用作引发表达式的操作数. 此对象通常用于传达有关错误的信息. 通常,应使用在标准库中定义的 std::exception 类或某个派生类,或者,如果这些都不适用,则从 std::exception 派生自己的异常类. try 块封装一个或多个可能引发异常的语句. 一个或多个 catch 块紧跟在 try 块之后. 每个 catch 块指定它能处理异常的类型. 以下语法显示一个示例…

【Java学习笔记之三十三】详解Java中try，catch，finally的用法及分析

这一篇我们将会介绍java中try,catch,finally的用法 以下先给出try,catch用法: try { //需要被检测的异常代码 } catch(Exception e) { //异常处理,即处理异常代码 } 代码区如果有错误,就会返回所写异常的处理. 首先要清楚,如果没有try的话,出现异常会导致程序崩溃.而try则可以保证程序的正常运行下去,比如说: try { int i = 1/0; } catch(Exception e) { ........ } 一个计算的话,如果除数…
