  <p>I need to install the latest version of J2SE. So right now I am at the specified link below trying to figure out how to proceed. The author of the book I got says to get the updated version of J2SE. I found JSE7u5 which I guess is the updated version. But on the right side of the page(which is still the specified link below) JDK and JRE show up. Am I supposed to install both of these to crete the full JSE package? Also I am running on a Mac.</p>
