Where is JDK 7 after Mac OS X Install?

Problem: I just installed JDK 7 on Mac OS X, but it seemed like nothing happened. What do I do, where is it installed?



Solution: Everything is explained in the ReadMe. Unfortunately, I missed the link on the last screen of the installer. So here is the link in case you missed it:

Basically, use the Java Preferences application in the /Applications/Utilities directory to choose which version of Java to use. Then open a Terminal window and you will see the JDK you selected is being used.
