Eclipse Quick diff feature

Both the Eclipse text editor and the Java Editor provide quick diff functionality. This allows you to quickly identify the difference between the currently edited version of the file and the reference version of the file.

If the Quick diff feature of the editor is not enabled, you can open the Preferences dialog and enter "Quick diff" in the Search box and click on the "Quick diff" option to make the appropriate settings in the right section.

If you make the appropriate changes in the editor, the corresponding markers will appear in the corresponding position of the quick difference ruler on the right side of the editor, and you can put your mouse on the editor to view the corresponding information.
