Test your Java code on-line !!!

But what is very nice is that you have possibility to choose the JDK. So, you can decide to run your code by using JDK 5.0, but also by usng JDK 6.0.

It's really simple to use.

• Go to that URL: http://www.zamples.com/JspExplorer/index.jsp?format=jdk16cl
• Update the sample class
• Click on the Run It button
• Your class is compiled and executed
• Result appears on the right

Hereunder a screenshot of a little java class that display the version of the JRE, but also the parameters given as input.

Please note that signature of the main method is public static void main(String... args) {}

If you compile it with an old JDK, it will never compile. That new notation has been introduced with Tiger (JDK 5.0)

Note also that they are using build 13 of the JRE 6.0.

I hope they will update the used JDK with the last build available on java.net. That would be really great.

• We would like to fully automate the update process using a Gentoo ebuild script. If anyone reading this would like to contribute such a script, we'd be delighted to run it as a cron job every night. That way Zamples would always be guaranteed to have the latest and greatest JDK 6 version for everyone to play with.

• OK, we've automated the updating of our JDK 6 support. Every 24 the public Zamples server checks for a new update of JDK 6, downloads and installs it if available. Have fun, and share your discoveries with the community!
