How to run single java files independently in Intellij IDEA or vscode?

Question

I need to run single java files independently in Intellij IDEA or vscode. Currently, when I run a single program both IDEs checks for other files.

For example, in the given image, I need to run ReversingString program only, but it doesn't run it and asks me to correct error in other java files.

How can I run a single file while ignoring other files. I checked answers to other similar questions here like editing run configuration but nothing is working.

I want all files in this folder to be independent/separate from each other.

Update: I found the solution :

All you need to do is to basically stop building the project.

For that click beside the run icon - "Edit/Run configurations" Click on modify option and check the option "Do not build before run" and now you can run a single file.

UPDATE:

This problem has been fixed in the latest version of vscode.

In VS Code, you only need to click proceed in the pop-up window to compile and run the current file normally.

Below is my file structure, I open myproject folder in VS Code.

myproject
├─ DemoOne.java
└─ DemoTwo.java

I have two errors in DemoTwo.java. When I run DemoOne.java, a pop-up window will appear. Click proceed to compile and run demoone normally.

Another way:

Install the Code Runner extension, then right-click on the DemoOne.java editing interface and select Run Code( Ctrl + Alt + N ). This will run the code using Code Runner, it will not compile all the files in the folder. Output results directly on the OUTPUT panel.
