Any book or article talking about the java references (s开发者_开发技巧trong, soft, weak,Phantom references)? How to use them (scenarios)?

Understanding Java (Strong, Weak, Soft and Phantom) References. Moreover, technically the best core java book, I found is, Khalid Mughals' certification book, A Programmer's Guide to Java. It is dated, indeed.

The Java Programming Language: Fourth Ed. has a few pages about them. It is a very good reference, that goes into detail on how the garbage collection is performed, and how references are involved.
