Eclipse Associated JDK Source code

SRC.ZIP:JDK Source code file (there is a directory where JDK is installed).

The RT.JAR:JDK class byte code package.

Eclipse is associated with Src.zip through the Rt.jar package.

I would like to see the source code hints as follows: You can see that Rt.jar is associated with Src.zip

Specific steps:

1.windown->preferences->java->install JREs;

2. At this point, the current system-installed JRE is displayed on the right, select the currently used JRE, and then edit;

3. Locate the Rt.jar in the "JRE System Libraries" and select it;

4. On the right there is the source Attachment, click on it, and then select "Src.zip" file in "External location";

5. End of the way OK;

View Source button: Left Ctrl + Source class (Example:calendar)
