I want the java update for the mac OS 10.7.3

Just run software update.

System Preferences -> Software Update -> Check now

If it shows a Java update, then install it.

If it DOES NOT show a Java update, then you either already the update installed, or you DO NOT have Java installed, so you do not need the update.

Hey, would you by any chance know how to check if the java software is updated? Is there a way to check without checking for updates in the app store? 🙂
