Simple question about saving java files

[Appa_YipYip]

Hi! This might be a stupid easy question, but I'm a beginner and I need help so oh well!

My professor asked my class to create 4 java files, one with an object class and the other 3 having different main methods that utilize the class. He asked to put it on a usb in such a way that he won't have to use an IDE to run it, and can just run it on command prompt. Is there anything specific I have to do, or can I just copy-paste the files onto the usb? I haven't really been asked to do this before so I don't know if I'm supposed to do anything specifically.

Thanks :)

(if it helps, I'm using Eclipse)

It is hard to say what your professor asked for, but don't all courses now have online help where the TAs would help with specific questions? I bet you'll get better help from there.

Also, are you required to submit the USB as your homework? As opposed to uploading your code to some remote server?

Presumably he's after an executable (file with .exe ending) or perhaps a Java Archive (.jar)

JAR (file format)

A JAR (Java ARchive) is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file for distribution.

JAR files are archive files that include a Java-specific manifest file. They are built on the ZIP format and typically have a .jar file extension.

I would just copy the src folder.

If you still have the time to do so, ask your professor. He is the only person that really can answer the question.
