The GC calculator gathers and records information from browsers. This enables the identification of problems and allows improvements to be made. Part of these datum are the version of Java Virtual machine JVM, and the Operating System the calculator is currently running on. See Explanation, below

Explanation

The JVM version is of particular interest to myself and most likely any Java programmer that codes applets for general Internet use. Java is an evolving language and new features are added at every release. These later features are however, are only usable if the JVM the applet is running on supports them. Probably the three most significant versions are
Java 1.0
The first, and now obsolete version of Java
Java 1.1
Improved performance and event handling model. This release is generally considered the baseline by professional programmers. It is also reckoned to be the newest version that one can generally expect widespread support in non-customised browsers.
Java 1.2, aka Java 2
Vastly improved UI Toolkit - Swing, and many other useful facilities. Most Java applications (not Internet Applets) are written using Java 2 features

The first table shows the JVMs used in browsers that have loaded the calculator. I believe these numbers confirm the contention that despite much publicity given to Java it is still only possible to code applets to the Java 1.1 standard.

The second table summarises the Operating systems in use. This is as reported by the JVM and may not be completely reliable.

Statistical summation began on 20th December 2003.
