How to check the Java version

To check the Java version a command prompt in Windows or a terminal in Linux/Mac needs to be opened.

In Windows XP go to Start Menu -> Run and enter cmd.exe. In Vista/Win7/Win8/Win10 go to the Start Menu, enter cmd.exe in the Start Search box and click on the search result cmd.exe.

For Linux check the application or system menus for a program that includes the name terminal or console. Different distributions put it different places. When one is found run it.

For Macs go to Applications -> Utilities and run the terminal application.

When a command prompt or terminal is opened enter java -version and something along the lines of the following should be returned.

java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode, sharing)

GUIquotes needs a Java version 1.5.0 or later to run which is the case in the above example.

If the results did not return a Java version most likely Java is not installed or not installed so it can be run anywhere. The easiest way to fix this is to install the Java SE Runtime Environment from www.java.com/getjava/.
