Java Download and Installation Instructions

You may want to print these instructions before proceeding, so that you can refer to them while downloading and installing Java. Or, just keep this document in your browser. You should read each step completely before performing the action that it describes. This document shows downloading and installing Java on Windows 7.

Java

The following instructions were composed for installing Sun Java 1.7.0_5 (aka Java SE Development Kit (JDK) 7, Update 5). The version you download may be newer. Note: Java is already installed as part of Mac OS X, so no further installation is necessary if you have recently purchased one of these machines. You can determine whether you have the right version by typing

  java -version

to the unix command prompt on Mac OS X; the response should be something like java version "1.7.0_5"; it does not have to be this exact update.

The Java download requires about 1 MB of disk space; keep it on your machine, in case you need to reinstall Java. When installed, Java requires about an additional 290 MB of disk space.
