Checking Current Java Version

     

It is not uncommon to have many different JREs running on the same machine at the same time. To check the current default version:

1. Open a command prompt.

2. Type java “version .

You will see output similar to this:

 Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b91) Java HotSpot(TM) Client VM (build 1.5.0-b91, mixed mode)
