# Generics

在任何重要的软件项目中，出现bug是日常。认真的计划，编码和测试可以减少bug的出现，但是bug总是时不时的出现在你的代码中。尤其是伴随着功能的新增你的代码量和复杂度也随之增加bug也随之而来。

幸运的是有些bug是容易发现的。比如，编译时bug就能被很早发现，你可以使用编译器的报错信息来确定问题所在并立即修复它。但是运行时bug会造成更大的麻烦，它们不会立即显现出来，当它们发生时，代码的位置可能和实际问题的原因相去甚远。

`Generics`（泛型）通过在编译时让你的bug更容易被检测而使得你的代码更加稳定，通过本章的介绍，你可以继续看`Gilad Bracha`的[教程](https://docs.oracle.com/javase/tutorial/extra/generics/index.html)
