Different versions.

One big difference between 1.0 and 1.1 was the way events and event listeners were handled. 1.2 added Collections. Version 1.4 added the keyword "assert".

You can find the release notes at java.sun.com for more details.

All of the differences are WAY too numerous to list here. However, The official Java web site contains all the documentation documentation you need about Java. For example, here is the index for docs about Java 1.4. If you scroll down the page, you can find Enhancements and Changes in Java 2 SDK v1.4.2 and New Features since J2SE 1.3 Platform. Each release of Java has similar documentation. You will probably have to search the archives to find information about versions older than 1.3. However, it is available, so don't give up.

While you are at it, please see my postings in the Java in general (intermediate) forum under the topic "Key Advantages of Java 5" regarding J2SE 5, aka Java 5, aka Java v. 1.5.

Regards,

Yeah, and the difference between 1.4 and 5.0 is a good 3.6
