The starter code for Java Practical exercise number 1 in CSCU9T4
This is a Netbeans project but you can import it to an IDE of your choice.
Instructions on doing so can be found by simply searching for:

[insert IDE name here] import Netbeans project

I have successfully imported to:

• Eclipse
• IntelliJ

Alternatively you can just checkout with Git and use any plain text editor.
I recommend:

• Notepad++
• Emacs (if you've used it before)
• Vim (again, if you've used it before)

Fork the repository to your own one before checking it out to your laptop/pc to work on.
That way you can use your own repository to keep control of versioning of your own code.
