First of all, I am very sorry, I have changed in this topic's first article. This will be the last part of this topic. On the one hand, I found that the outline listed in Sun's official document, the ranks of the following chapters are too broad, and some are usually usually used and considered. On the other hand, my time is indeed limited. If you really want to write, you may be similar to [J2SE 5.0] [3] virtual machines, can only talk more. Therefore, in this part of this topic, I will choose some more practical and characteristic updates from the rest of the highlights.
With the release of J2SE 5.0, many basic class libraries have updates, some new API libraries are introduced, which I think is more important and worthwhile (at least I am more interested) is below: New JDBC RowSet sub-interface and concurrent kit. We know one by one in the next topic article.
