为啥子这么多 commit 记录

下次记得翻译一篇新开一个分支，合并之后删除分支。master 分支用来同步，下次翻译再从 master 新开就好啦。#养成使用 Git 的好习惯#

-Default methods make it possible to add new methods to an interface without breaking all classes that implement that interface.
+默认方法使你可以在不破坏实现一个接口的所有的类的情况下，向接口中加入新的方法。


不破坏实现一个接口的所有的类的情况下 -> 不破坏实现了同一个接口的所有的类的情况下

不……原文也是可以读通的。在这里“一个”和“同一个”的意思是一样的。

原文确实是通顺的，我觉得这边可能是要强调一下这个接口的“同一个”，并且下面半句里用了“该接口”，个人感觉这样可能更顺畅一点？

我不理解。原文就不是表格啊。

英文原文是的，应该是在转化成 Markdown 的时候出现了失误。

可是markdown支持这个样子的表格吗？
