问题描述
这两个术语之间有什么实质性区别吗?我了解 JDK 代表 Java Development Kit，它是 SDK(软件开发工具包)的子集.但是指定Java SDK，应该和JDK一样.
Is there any substantial difference between those two terms?. I understand that JDK stands for Java Development Kit that is a subset of SDK (Software Development Kit). But specifying Java SDK, it should mean the same as JDK.
推荐答案
从此维基百科条目:
JDK 是一般意义上的软件开发工具包 (SDK) 的一个子集.在最近发布的 Java SE、EE 和 ME 的描述中，Sun 承认根据他们的术语，JDK 构成了负责编写和运行 Java 程序的 SDK 的子集.SDK 的其余部分由额外的软件组成，例如应用服务器、调试器和文档.
The JDK is a subset of what is loosely defined as a software development kit (SDK) in the general sense. In the descriptions which accompany their recent releases for Java SE, EE, and ME, Sun acknowledge that under their terminology, the JDK forms the subset of the SDK which is responsible for the writing and running of Java programs. The remainder of the SDK is composed of extra software, such as Application Servers, Debuggers, and Documentation.
额外软件"似乎是 Glassfish、MySQL 和 NetBeans.此页面比较了您可以为 Java EE SDK 获得的各种包.
The "extra software" seems to be Glassfish, MySQL, and NetBeans. This page gives a comparison of the various packages you can get for the Java EE SDK.
