推荐答案

这要看情况。文字字符串是拘留每默认，所以即使你的应用程序不再引用它它不会被收集，因为它是由内部实习结构引用。其他的字符串是就像任何其他管理对象。只要他们是由您的应用程序不再引用他们有资格进行垃圾回收。

That depends. Literal strings are interned per default, so even if you application no longer references it it will not be collected, as it is referenced by the internal interning structure. Other strings are just like any other managed object. As soon as they are no longer reference by your application they are eligible for garbage collection.
