java里面也有字符串池，只是你们这些只顾着 业务流程设计 开发的傻比没注意到。

Java的：

public String intern()
Returns a canonical representation for the string object.
A pool of strings, initially empty, is maintained privately by the class String.

When the intern method is invoked, if the pool already contains a string equal to this String object as determined by the equals(Object) method, then the string from the pool is returned. Otherwise, this String object is added to the pool and a reference to this String object is returned.

It follows that for any two strings s and t, s.intern() == t.intern() is true if and only if s.equals(t) is true.

此问题很弱……

不遵循重构也就罢了，毕竟重构对效率有影响
不考虑字符串池也罢了，毕竟损失的效率不多
可是不考虑编码规范也至少写个简练通俗点的代码吧，让我看得头晕的代码，损失的是我读代码的效率

你问java的GC设计者吧。

所以不但要做项目经理，还要做到技术比业务高的境界
