In view of the recent Malware issue with Mac's and Java, how do I tell if I might have already downloaded the the fix put out by Apple?
Open the Java Preferences.app (find it in Applications/Utilities/). The General tab will show you the version of Java you have installed in the far right column.
If you have the latest, it should say 220.127.116.11.
Hope that helps.
