Thread: How to make an Eclipse program stand alone and more

This will probably come off as a confusing or illogical question, but I'll ask it anyway!

I have made a Java program using Eclipse, and I would like to make it so that some variable values are stored after the program is closed.
First off, do I need to make the program a ".exe" for this to work?
If so, how?

I need only to store a few integers, some arrays, and a couple strings.

I do apologize if this question is incorrectly categorized, or just doesn't make sense.

Small (but important) point: The program's variables are stored BEFORE the program closes. No, you don't need to make the program an .exe. That extension means something in the Windows OS environment, but it doesn't mean anything in a Mac or Linux OS, except the name of a program that won't run.

Important program variables that will be used the next time the program is run are typically stored in a file on the running or host computer's non-volatile mass storage, on a network server, on the cloud, somewhere the program can access when it next starts. Learn about Java I/O, especially reading from and writing to a file.

What does I/O mean?

What happens if you Google 'java i/o'? Please, don't be helpless.
