問題描述
這兩個(gè)術(shù)語(yǔ)之間有什么實(shí)質(zhì)性區(qū)別嗎?我了解 JDK 代表 Java Development Kit，它是 SDK(軟件開發(fā)工具包)的子集.但是指定Java SDK，應(yīng)該和JDK一樣.
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.

從此維基百科條目:
JDK 是一般意義上的軟件開發(fā)工具包 (SDK) 的一個(gè)子集.在最近發(fā)布的 Java SE、EE 和 ME 的描述中，Sun 承認(rèn)根據(jù)他們的術(shù)語(yǔ)，JDK 構(gòu)成了負(fù)責(zé)編寫和運(yùn)行 Java 程序的 SDK 的子集.SDK 的其余部分由額外的軟件組成，例如應(yīng)用服務(wù)器、調(diào)試器和文檔.
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.
額外軟件"似乎是 Glassfish、MySQL 和 NetBeans.此頁(yè)面比較了您可以為 Java EE SDK 獲得的各種包.
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.
這篇關(guān)于JDK和Java SDK的區(qū)別的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
