[The debug mode in the idea has modified the java class and turned off the Reload Changed Classes for *** pop-up box. How to restore it]

   In DEBUG mode, I accidentally checked "Do not show this dialog in the future" and the pop-up box will not appear. How to restore this function?

1. In IDEA, open “File” –> “Settings…”

2. Select “Build, Execution, Deployment”–> “HotSwap”

Select "Ask" for Reload classes after compilation, save and exit.
