problem: Java uses shortcut keys to view source code display sources not found
Cause of the problem: The missing src.zip file in the JDK directory is only javafx-src.zip
src.zip File: Source code for all Java classes download Src.zip address: Https://pan.baidu.com/s/1_SdoulFkFUd3Je01zrw8qQ
1. Copy the Src.zip file to the installed JDK directory
2. The right side of "Installed JREs" is the list pane, listing the JRE environment in the system, selecting your JRE, then clicking on "Edit ..." on the edge, a window will appear (edit JRE);
3. Select this entry for the Rt.jar file: the "+" sign on the left side of the "C:\Java\jdk1.5.0_04\jre\lib\rt.jar" point expands it (the actual JDK installation path is whichever you are);
4. After expanding, you can see "source Attachment: (None)", point this item, point to the right button "Source Attachment ...", select the "src.zip" file under your JDK directory;
5. The end of the "OK" point.
The above for me to meet the above problems, Baidu found the way to summarize.
