The Java Update is a feature that keeps your computer up-to-date automatically with the latest Java releases. Installing the Java Runtime Environment automatically installs the Java Update feature.
The Java Update feature connects to java.com at a scheduled time and checks to see if there is an update available.
One of the main reasons for installing a Java update is to provide the programs on your computer that use Java with access to any additional functionality a new version of the platform includes. Java is constantly evolving and making it possible for programs to carry out an increasing range of tasks. Although you are unlikely to be aware of the details unless you are a programmer, you will benefit from access to these improvements in the programs you use.
