How do I import JDK source code into eclipse or Intellij idea?

The main is to the JDK involved in the multi-threaded source into IntelliJ idea;

Facilitate the source code annotation, tracking, and drawing UML diagram;

The main steps are as follows:

1. Download JDK Source code

Mode one: Download directly from the address below (I am using this method)

Https://github.com/fanhongtao/JDK

Method Two: Obtained from the JDK's Rt.jar package, e.g. Jdk1.8.0_112\jre\lib\rt.jar

Decompression Rt.jar

2. Using IntelliJ idea to create a common Java project

3, copy the source code about multithreading,

Note that copying is not recommended to copy only java\util\concurrent this package//otherwise, the package path in the class is not correct,

The entire Java package needs to be copied to the newly created Java project,

In this way, the JDK source code can be annotated, updated, parallel to the source tracking
