java代码统计器，设置你的workspace，即可统计你的所有代码，写了两个版本，一个多线程，一个迭代实现，最后却发现迭代的速度快得多，因此保留了迭代的版本。

此程序仅供娱乐，因为代码量不能说明任何问题-java code for statistical device, set up your workspace, you can statistics all your code, written in two versions, a multi-thread, an iterative implementation, the end, they found that the speed of iteration is much faster, thereby preserving iterative version. This procedure only for entertainment
