I was trying to figure out just for kicks and I didn't see that at first. First year programming in Java

Worst part of Java is my professor has tests on paper. I can't compile on that!

You should work on debugging your code in your head. It's an extremely valuable skill and helps you write better code the first time. Something I've been trying to get better at myself.

For the fun of it. Im using netbeans. How would i go about making it into an exe

Djibrille

· #15 · Mar 12, 2009

Why would you want to make an exe from java code you would lose the portability that way.Java was created so that you can run the same .class file on different OS-es(eg: Xp, Vista, Linux even OS2) as long as you have the Java virtual machine installed.
But if you really want to make an executable I beleive there are some utilities that can do that, just google for it.And no, Netbeans won't help you do that.
