回复了 Newyorkcity 创建的主题 › 问与答 › Java 中，一个 final 的 List 变量，被往里加了元素，算不算违反了 final 这个关键词在这里暗示的约定？
https://docs.oracle.com/javase/specs/jls/se7/html/jls-4.html#jls-4.12.4
If a final variable holds a reference to an object, then the state of the object may be changed by operations on the object, but the variable will always refer to the same object.
