I am planning to start some Java mobile phone development. 我正计划开始一些Java手机开发。 I downloaded the wireless toolkit, but it asks for the Java SE SDK. 我下载了无线工具包，但它要求Java SE SDK。 I have got to this page - http://java.sun.com/javase/downloads/index_jdk5.jsp . 我已经到达此页面-http://java.sun.com/javase/downloads/index_jdk5.jsp 。 Is a JDK the smae as an SDK? JDK是smae作为SDK吗？ what do they stand for? 他们代表什么？ On the page I think I will need to download the "JDK 5.0 with Java EE". 我认为在页面上，我将需要下载“带有Java EE的JDK 5.0”。 What does the Java EE do for me?

Also, are there any good tutorials for this? 另外，有没有很好的教程呢？ (I am using windows) （我正在使用Windows）

3 个解决方案

JDK = Java Development Kit. JDK = Java开发套件。 It's the Java SDK (software development kit). 它是Java SDK（软件开发工具包）。 One and the same. 一而同。 One thing you may see in the future that is confusing is the JRE - the Java runtime environment. 您将来可能会看到的一件事令人困惑，那就是JRE-Java运行时环境。 This is all a non-programmer would need to run Java on their machine. 这是非程序员在其计算机上运行Java所需的全部。 But a developer would need the SDK. 但是开发人员需要SDK。

You probably don't need Java EE. 您可能不需要Java EE。 That is used mainly for web development. 那主要用于网络开发。

Personally, unless you are keen on doing Blackberry development, if you want to do Java mobile development I would recommend looking into Google's Android instead. 就个人而言，除非您热衷于进行Blackberry开发，否则如果您想进行Java移动开发，我建议您改用Google的Android 。

If you are using J2ME 3.0 then here are some requirements: Java SE Development Kit - JDK 1.6 or higher 如果使用的是J2ME 3.0，则有一些要求：Java SE开发套件-JDK 1.6或更高版本

So, SDK is SE Development Kit. 因此，SDK是SE开发套件。

If you are using the Wireless toolkit 2.2 then here are the requirements: JavaTM 2 SDK, Standard Edition (J2SE SDK), version 1.4.2 - if you plan to do actual development, or JavaTM 2, Standard Edition Runtime Environment (JRE), version 1.4.2 - if you only plan to run the demonstration applications. 如果您使用的是无线工具包2.2，则要求如下：JavaTM 2 SDK，标准版（J2SE SDK），版本1.4.2-如果您打算进行实际开发，或者是JavaTM 2，标准版运行时环境（JRE），版本1.4.2-如果您仅计划运行演示应用程序。

Java EE you won't need, unless you are writing some enterprise application that runs on the server-side. 除非您要编写一些在服务器端运行的企业应用程序，否则您将不需要Java EE。

NetBeans is probably the best IDE for J2ME development . NetBeans可能是J2ME开发的最佳IDE 。 Start with this thread and you should be on your way. 从这个线程开始，您应该已经准备好了。
