Java版SE，EE和ME [英] Java Editions SE, EE, and ME

问题描述

问候，



我是Java编程语言的新手，我知道有四种Java编程语言平台

Java平台，标准版（Java SE）

Java平台，企业版（Java EE）

Java平台，微型版（Java ME）

JavaFX



我已经通过以下链接了解了这四个平台



http://www.oracle.com/technetwork/java/javase/overview /index.html [ ^ ]



但是我想通过专家确保Java EE拥有比Java SE更多的包，而Java ME包含的包比Java SE少而且肯定比Java EE。另外我需要知道在哪里可以找到这些不同包的列表。



我从下面的linke下载了Java SE Development Kit



http://docs.oracle.com/javaee/6/firstcup/doc/gkhoy.html [ ^ ]



我也下载了Eclipse IDE。我是否可以编写连接到数据库的应用程序，或者我必须下载Java EE SDK，因为它包含的包又包含可以连接到数据库并执行查询等的类。这些包不存在于Java SE SDK和同样的问题，如果我想为移动设备编写应用程序，我是否必须下载Java ME SDK或者我可以开始编写这样的应用程序而无需下载这些SDK （s）？



提前谢谢

Greetings,

I am new in Java programming language and I know that there are four platforms of the Java programming language
Java Platform, Standard Edition (Java SE)
Java Platform, Enterprise Edition (Java EE)
Java Platform, Micro Edition (Java ME)
JavaFX

I already read about the four platforms through the below link

http://www.oracle.com/technetwork/java/javase/overview/index.html[^]

But what I want to make sure of it by experts here that Java EE has more packages than Java SE and Java ME has less packages than Java SE and definitely than Java EE. Also I need to know where can I find a list of these different packages.

I've downloaded the Java SE Development Kit from the linke below

http://docs.oracle.com/javaee/6/firstcup/doc/gkhoy.html[^]

I've download the Eclipse IDE also. Can I write application(s) that connects to database or I have to download the Java EE SDK as it contains packages which in turn contains the classes by which I can connect to the database and execute queries etc. and these packages do not exist in Java SE SDK, and the same question if I want to write application(s) for a mobile device(s) do I have to download the Java ME SDK or I can begin write such application(s) without the need to download these SDK(s)?

Thanks in advance

推荐答案

如果您是Java新手，那么我建议你坚持使用Java SE并忘记其他两个，直到你掌握了编程技巧。完成各种教程并为自己尝试一些真实的项目。

If you are new to Java then I suggest you stick with Java SE and forget about the other two until you have developed your programming skills. Work through the various tutorials and try some real projects for yourself.
