Java如何入门？高手指点，发言有分！

[lazyfish]

最近我想学JAVA，但不知道如何开始？我有几个问题不明白：
1、java,java2,j2ee,j2se,j2me,等等有何异同？
2、用哪个开发环境最好？
3、推荐学习他们的文章或则网站什么的？

[hello_world]

去sun网站当

[xutaiqing520]

先看一些Java的基础书籍，如Thinking in java。
至于JDK，可以直接到java.sun.com网站上下载。

[faintagain]

java编译器从sun公司就可获得，推荐jdk1.3版，不要用1.4
网址java.sun.com。
入门书<<think in java>><<java2 核心技术>>卷一、卷二
关于jsp,servlet,ejb这些技术最好到sun公司下载资料，市场上书很多，但大多都是相互抄袭，质量低略。
然后熟悉weblogic,websphere的使用，在熟悉db2,oracle,sqlserver的基本
使用，做项目时大多离不开这些
这也是我学java的大概过程

[kkjava]

java,java2,j2ee,j2se,j2me是JAVA的相对不同开发环境而发行的不同版本！

它们是不同开发环境，没什么好坏！

sun.java.com
www.cnjsp.com
www.ChinaJavaWorld.com
www.code-labs.com
www.cnjavaclub.com

[yuanqigao]

java,：一门语言。
java2,第二版。
j2ee,企业EJB，大型系统集成
j2me：主要用于手机等家用电器。

我应该从那里开始学java?该怎么学？那里有JAVA的编译其（JDK）？
