IsNegative.java

This program was created once again using the old school Java GUI known as JOptionPane.

Unfortunately, the name of this program should’ve been return negative. Apologies for the confusion!

It checks if the number is negative and if not, make it negative.

The code has been modified slightly and now uploaded to the site.
