Running .jar in command prompt

[wonstatus]

I'm a little confused if you can actually do this, I set the program up not using a GUI because it doesn't need one, so I am trying to figure out if I can make the program run in command prompt with user interaction.

Example: "What is 2+2?"
User input: "4"
"Correct!".

I hope this makes enough sense.

I think it should work. Have you tried it?
I've never tried reading from the console from a program in a jar file, so I don't know if it will work.

Yes I have tried, but the .jar wont open. When I open command prompt and test it using "java ProjectName" it runs fine, I just can't get the .jar to open command prompt.

how are you executing the jar file?
Open the command prompt and enter: java -jar JARFILENAME.jar

Or do you want to display a text field and allow the user to type input into that?

I opened command prompt and typed that in, and it worked, but how would I make it do that when the user opens the .jar file?

It might work if you used a batch file.
But why stay with command line I/O?
Write a simple GUI with a text field and a button.

I stayed with the command I/O because I figured at first it would be easier. I will see how it goes with a GUI. Thanks!

The GUI will be much better.
There are plenty of sample here on the Forum. Use Search for JFrame or setDefaultCloseOperation for examples
