Introduction
Here in this article we get an explanation about the main characteristics of Java that are coming in Java SE 6. The currently planned items are displayed here. Many are already integrated, and you can try them out yourself by downloading the most recent build from the snapshot release site. We try to estimate when you can expect to see in a snapshot release those items that are still in development. When a status line reads, for example, "Delivered in b39," it means that the feature was integrated in build 39. A new build is posted to the snapshot release site weekly. The growth of the build number in each week is explained here.
