How to tell which version of java is running in linux (Ubuntu)

May 10th, 2010

Command line

To find out which version of java is installed, type

java -version

in a terminal window. This will give something like this:

java version “1.5.0”
gij (GNU libgcj) version 4.2.4 (Ubuntu 4.2.4-1ubuntu3)

Browser

You can also visit www.java.com’s Verify Java Version page. On this page, there is a pleasingly big red button that you can click which will tell you what version of java is installed.

Pressing the pleasingly big red button will tell you something like this:

Your Java version is 1.5.0_22

Of course, if one isn’t running the latest and greatest version, this page tells you to install the most up-to-date version, but I usually prefer to wait until there is an official Ubuntu update.

Hello World.

Well, there are lots of things that I want to remember.

Just in case they don’t all stay in my head, I’m putting them here. Some of this is pretty specific to my computers, but I suppose it’s possible that some of this might be helpful to someone else one day. (If you’re here and it’s not, erm…I’m sorry!)
