- 实验12 异常处理 12.1 实验目的 (1)掌握异常处理的编程特点。 (2)了解Java异常分类层次,常见系统异常。 (3)了解自定义异常的定义及方法异常的抛出与处理。 12.2 知识要点 Java把异常加入Java语言的体系结构,为异常定义了类和关键字,简化了错误处理代码。将错误处理从正常的控制流中分离出来,对错误实施统一处理。 12.2.1异常处理结构 try { 语句块; } catch (异常类名1 参变量名) { 语句块; }

- 一个try-catch语句后面也可能跟着一个finally语句,不论try代码块是否顺利执行完,它都会被执行。 try { statements -A try-catch statement may also be followed by the back of a finally statement, regardless of whether the try code block the smooth implementation of END, it will be ex
catch
- 捕获异常方法 运行结果: <调用doSth()方法开始 > <调用loadClass()方法开始 > <try的自述:在这里监控可能出现异常的代码 > <catch的自述:出现异常在这里处理> <finally 的自述:不管是否出现异常,最后都要执行到这里 > <调用loadClass()方法结束 > <调用doSth()方法结束>-Catch exceptions method
