How to check for the latest version of java

I want to make a java-based GUI tool that checks for the latest version of java available online,and compares it to the version currently installed

I already know how to check for the version currently installed on the machine

I don't know about the part where you check for the version available online

+1  A: 

Have you looked into java web start for deploying your application? It will automatically perform version checks and perform the installation if a new version is needed.

No,and I want to write code that checks for the version myself,I'm not familiar with the JNLP technology

I should have known. Your username suggests that you might have a strong fear of JNLP technology :)

JNLP checks the application's version, not Java's version.

I want to say that via the JNLP file, you can also specify that the application requires a particular version of java. If that version is not installed, jnlp will either download it or direct the user to a site where they can download and install it.

A particular version of java doesn't mean that it'll be the latest available,right?

This web based Java Tester does what you want to do.

The author of the Java Tester keeps track of the latest version manually. I think you would have to do the same.
