在执行中实习生池现有字符串的字符串连接，是一个新的字符串输入到实习生池，或者是引用返回到现有的字符串中的实习生池？根据这篇文章，String.Concat和StringBuilder的将插入新的字符串实例进实习生池？

When performing string concatentation of an existing string in the intern pool, is a new string entered into the intern pool or is a reference returned to the existing string in the intern pool? According to this article, String.Concat and StringBuilder will insert new string instances into the intern pool?

任何人都可以解释如何串联工作的实习生池？

Can anyone explain how concatenation works with the intern pool?

推荐答案

如果您创建新的字符串，他们不会自动投入实习生池，除非您连接常量编译时，在这种情况下，编译器会创建一个字符串结果和实习生，作为JIT过程的一部分。

If you create new strings, they will not automatically be put into the intern pool, unless you concatenate constants compile-time, in which case the compiler will create one string result and intern that as part of the JIT process.
