3. RuntimeException

Thinking in Java
Chap10 通过异常处理错误
将"描述实际工作的程序代码" 和"处理错误的程序代码"隔离开来。
只要有任何异常被抛出， 异常处理机制便会找寻第一个参数类型于该异常类型相符的处理程序。 找到第一个catch类型符合的处理之后， 查找处理横线的动作便终止。 和switch case 不同， 在switch case中你得为每一个case子句加上break，才能避免继续逼进其他case。
e.fillInStackTrace()
RuntimeException
如果某个RuntimeException 一路往外传递至main()而未能被捕捉，那么当程序终止时便会针对该异常，调用printStackTrace()

如何获取程序的stack trace

设计就是创造力的一种妥协。
