Why doesn't it work correctly after compiling a java project?

Question

Java

In general, I had a problem with the fact that everything works fine in the code editor, but after compiling the jar file, something goes wrong. Does anyone know what to do?


PS Guys, I realized that the problem is not in the jar file, but in the bat file that I created to run the program. But if I do not create a bat file, then I have no idea how to run a console application without a code editor.
