In this way of thinking about it, of course staticMethod() can only see static members of Outer. But if that were how javac works, then referencing an instance variable in a static method would result in a "name cannot be resolved" error. What really happens is that the name i...

opening files, etc. Were String not immutable, a connection or file would be changed and lead to serious security threat. The method thought it was connecting to one machine, but was not. Mutable strings could cause security problem in Reflection too, as the parameters are strings. ...
4) Another reason ofWhy String is immutable in Javais to allow String to cache its hashcode, being immutable String in Java caches its hashcode, and do not calculate every time we call hashcode method of String, which makes it very fast as hashmap key to be used in hashmap in Java. ...
