现在这个网址的网页上写着是JDK 6请问这个版本和1.5那种版本有什么关系？这个版本是做什么用的？谢谢～

You already saw the abbreviation JDK for Java Development Kit. Somewhat confusingly, versions 1.2 through 1.4 of the kit were known as the Java SDK (Software Development Kit). You will still find occasional references to the old term.
Next, you'll see the term "J2SE" everywhere. That is the "Java 2 Standard Edition," in contrast to J2EE (Java 2 Enterprise Edition) and J2ME (Java 2 Micro Edition).
The term "Java 2" was coined in 1998 when the marketing folks at Sun felt that a fractional version number increment did not properly communicate the momentous advances of JDK 1.2. However, because they had that insight only after the release, they decided to keep the version number 1.2 for the development kit. Subsequent releases were numbered 1.3, 1.4, and 5.0. The platform, however, was renamed from "Java" to "Java 2." Thus, we have Java 2 Standard Edition Development Kit version 5.0, or J2SE 5.0.
For engineers, all of this might be a bit confusing, but that's why we never made it into marketing.
