1、我知道java现在分j2se、j2me、j2ee三个方向。我想知道这几个的具体的含义，它们都是作什么用的，它们的区别，以前我见过一个这样的文章，不过那时没想学java，所以没在意。J2SE : Java 2 Standard Edition 基础
J2EE : Java 2 Enterprise Edition (大的)企业级
J2ME : Java 2 Mobile Edition （小的）用于手机/PDA
2、java的主流开发工具是什么，哪有下啊？
JBuilder/Eclipse
google啦
3、请个小弟推荐几个不错的java网站和论坛，谢！！！

J2SE : Java 2 Standard Edition 基础
J2EE : Java 2 Enterprise Edition (大的)企业级
J2ME : Java 2 Mobile Edition （小的）用于手机/PDA
我还有点不太懂，能说的具体详细点吗？分不够可以再加！！！谢！！！
一开始学习java的基础，当你打好基础选一个方向：J2EE : Java 2 Enterprise Edition (大的)企业级
扩充标准版用于企业级开发
核心是EJB还有好多APIORJ2ME : Java 2 Mobile Edition （小的）
比标准版类库小用于 手机/PDA...
建议J2SE好好学，万丈高楼平地起
me c->c++->oop->J2SE->J2EE(超菜)^_^
