.Class files won't update!

Hello!

I'm having an issue with compiling my Java-programs using cmd. It worked fine until suddenly the program did not get the new changes I did in the code, so when I ran a program I was certain would work, It was simply giving errors from a previous state in the code development.

I then tried to delete the .class files and recompile my program. Then the changes were made, and the program worked!

Any idea why these .class files stopped automatically updating? Is there anything I can do to make it work again, without having to delete the .class files between each compile?

Thanks!

Are you working in a Treehouse workspace? Because that has happened to my from time to time too. I simply closed the Workspace and reopened it and then it worked.

No, I'm just using a simply text editor (Visual Studio Code) and I'm compiling my programs using the command prompt on windows.
