Let’s start by making the following point clear: We love debuggers, and we believe that if you are not using one, purposely or out of habit, you are
not as productive as you could be.

You will find quantities of developers who basically think that they are too good for debuggers. They believe that the code they write is bug-free,
but whenever a few bugs creep in, they think that sprinkling a few System.out.println statements here and there is always good enough to find and fix their bugs. These developers are missing out on an extremely powerful tool that, if used in a careful and timely way, can save countless hours of bug chasing.

让我们从明确观点开始：我们喜欢调试器，我们相信如果您没有使用调试器，不论是故意的或是没有习惯，您就没有达到原本可以达到的开发效率。

您会发现许多开发者认为，他们很优秀，不需要调试器。他们相信他们写的代码是没有缺陷的，但是当一些缺陷出现时，他们认为插入一些System.out.println就足够发现并修复缺陷了。这些开发者错失了一个极为强大的工具，如果小心、及时地使用这个工具，可以节省大量的缺陷追踪时间。
