3.2 错误处理
首次编写一个类就编得很完美是极其罕见的。在大多数情况下，事情往往会出错。任何不为问题做计划的开发者都是在招致灾难。
假如想在代码中加入识别错误和处理错误的能力，有好几种方式。在Java Primer Plus（ISBN：9781571690623）一书的第11章，Tyma、Torok和Downing指出在程序中有三种基本的解决方案来处理发现的问题：修复问题、通过压制来忽略问题，或以合适的方式退出运行时。Object-Oriented Design in Java（ISBN：9781571691347）一书中的第4章，Gilbert和McCarty解释了异常处理的几个选择：
·忽略该问题——这不是好主意！
·检查潜在的问题，当发现问题时中止程序。
·检查潜在的问题，捕获错误并试图修复该问题。
·抛出异常（通常这是处理异常的最佳方式）。
下面详细讨论了这些策略。
