.jar files not working

I have some code in Java that I'm trying to turn into an executable file, but no matter what I have researched, watched, or tried, nothing seems to get either the .jar file or the .exe file running. Does anyone know how to fix this?

hello again, sorry for not replying. as you said there the jar file also isnt running. have you set an entry point for the jar files ? you can check by opening Manifest.mf in Meta-inf inside the jar. and look for Main-Class

Taste What do I do after that? Also, when I double click MANIFEST.MF in WinRar, it says "How do you want to open this file?"

use notepad, its just a textfile. just to chect that the main class for the jar is defined. its common that jar doesnt have an entry point.

it meant the jar corrupted or its not found. are you sure you're running from same directory as the jar file ?

Taste I ran it from Command Prompt, so going by your words, I assume I had to do it somewhere else?

from the folder use shift right click. then choose open cmd. from there a cmd will appear, then run the the jar file.

I tried exporting the code from the Eclipse IDE as a executable JAR file multiple times and turned them into executable files, but none of them work
