Mutable for those classes that cannot directly change the contents of the class, is an extension, such as the value of the class, does not involve pointers, there is no Mutable subclass, perhaps because it can directly modify its own values.

In other words, like a string such content and address is different and can be changed storage, in the high-level language, more concerned about the content changes, especially like Java has been "reference" to dilute the concept of pointers, and the actual inside is the operation of pointers such things, I also estimate.
