Question 27 (2024):

Submission reference: IN3672

Good day. I am having issues with the JAR file we are meant to make to submit the assignment 1. Whenever I create it and save it unto my laptop and I try to open it, it never opens. I save it as a JAR file but when I click on it, it doesn't open, please is there any reason for this sir?

Answer 27:

You cannot open a JAR file on the desktop, but if you use BlueJ's Project/Open ZIP/JAR menu you can check that the files are in it.
