@MuhammadimYusoff you may want to take a look at #1147 (comment)

I have tried it but also failed, the 'import javax.swing.*' line still have error.
I have saved the settings.json, quit VSCode and open up VSCode again but the error still there.
BTW is 'javax.swing.' and 'java.awt.' both of them GUI related libraries?
Other threads says about conflicting libraries but I am not sure about this one.

I can't reproduce the issue. Could you attach a project example?

@snjeza I think my system does not automatically set PATH for JVM, as per se the problem persist.
but as I am looking at my terminal nothing mentioned about JVM is not setup or related to it, but as I setup the PATH, the error still there, but at runtime the code running fine after I clean up the JAVA cache and all.

I have the same problem. However, JOptionPane still works though.

Do I need to add javax.swing jars to classpath?

in vscode:
go to settings, search for java , scroll down to "Java › Completion: Favorite Static Members"
click in "edit in settings.json" and delete this peace of code(or comment it in case it doesn't work)
//"java.addExports": [
//"javax.swing",
//"java.awt"
//],

----------SOLUTION----------
Go to settings.json and add the following lines:
"java.addExports": [
"javax.swing",
"java.awt"
],
Then, restart Visual Studio Code !!

This workaround seems to have fixed it for everyone, and is in fact the right thing to do.
