If there is, click on the Edit button and make sure that this variable
reflects precisely the path to your JDK folder. In both cases, the result should be
similar to this:
Chapter 2

Next, find the PATH variable in the same lower pane (the case doesn't matter).
Probably, it will already have some value, so you can append the path to the \bin
subdirectory of the JDK, separating it from the other paths by semicolon, as shown in
the following figure:
Close all dialogs by pressing OK. If everything was done properly, you should be
able now to check the version of javac, as explained above.
Configuring environment for Mac OS X
You will need to edit the .bash_profile file which is located in your home directory
(something like /Users/YourUserName/.bash_profile). The dot in front of the file
name means that it is a hidden file, so Finder will not display it.
There are different ways to edit this file. The one that I prefer is to use the
TextWrangler editor that can be downloaded for free from http://barebones.com/
products/textwrangler/.
Start TextWrangler and in the menu select File | Open Hidden..., and you will be
able to find, open and edit your .bash_profile easily.
All you will need to do is to add this single line of code:
export JAVA_HOME=/usr
This is where Java is installed by default on Mac OS X.
