How to change the CodeRunner .class file creation from same working directory of the java file in vs code?

I am currently using vs code to run my java files.
But when I use coderunner and run my java file it creates a .class file for every class in the same directory of my java file. Which gets messy how can I get rid of that?
I am ok with uninstalling the coderunner but in that case the java file errors doesn't show up properly and build fails.

Uninstall Code Runner and choose Java: Create New Project from Command Palette.
Create a no build tools project and coding in .java files which stored in folder src, then all the generated .class files will be stored in folder bin by default.
About the compilation errors, please post code snippets for further solution.

Install Test Runner for Java or Extension Pack for Java extension both by Microsoft. Better would be to go with an extension pack.

Java class can't read the jar file

i'm using eclipse noen and i've created a jar file contains only one java file. but when I added to the application library it still can't be seen.

Can you post the strutcture or an example of the contents of the JAR file?
JAR files should contain compiled java classes, not ".java" files.
If you are using Eclipse, create the JAR file by exporting the project.
