JDK1.8 source code analysis read source of order 02

Preamble: Read the JDK source code should be where to start, a planned, step-depth study of it?

Here's sharing a good source to learn the order of the article, when we re-read to the source, a guiding sign, but will not get lost.

Many in java jdk junior partner will read the source code, but does not know where to read from. Some fragmented learning, there is no link between knowledge and mutual knowledge, not knowledge. The following is a small series finishing reading the source code normally required range.
