E.5 Checking Current Version

It is not uncommon to have many different JREs running on the same machine at the same time. These can be installed manually or by associated programs (such as IDEs). To check the current version, do the following:

1. Open a command prompt

2. Type java -version

3. You will see output similar to this:

    Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)  Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
