Postscript

vscode is more suitable for writing small project code. If it is a large project, you still need to use that one More professional software, such as eclipse. I made a small game at the time, which was a project built using eclipse. It is also easier to find bugs. You can also add libraries, such as jl-1.0.1.jar, and I don’t know how to use vscode. After adding libraries and setting up the project, I often write about bugs that cannot be found. It is more comfortable for me to continue to use vscode to write, and debugging is also more convenient.

Attached is a small game I wrote. Due to the path problem, I can only put it on the desktop and run it and cannot change the folder name. It should be able to be changed in the .classpath file. Let’s see if it can run. It’s fate (^_−)☆.
