1、Eclipse：
Eclipse 是一个开放源代码的、基于 Java 的可扩展开发平台。就其本身而言，它只是一个框架和一组服务，用于通过插件组件构建开发环境。幸运的是，Eclipse 附带了一个标准的插件集，包括 Java 开发工具（Java Development Tools，JDT）。
2、MyEclipse：
MyEclipse是Eclipse的升级版，也是一款功能强大的J2EE集成开发环境，由Genuitec公司发布，提供免费版和收费版。被誉为最好用的Java IDE之一。
MyEclipse 是对Eclipse IDE的扩展，利用它可以在数据库和JavaEE的开发、发布以及应用程序服务器的整合方面极大的提高工作效率。
3、IntelliJ IDEA：
IntelliJ IDEA是一款综合的Java 编程环境，被许多开发人员和行业专家誉为市场上最好用的IDE之一，与MyEclipse齐名。
它提供了一系列最实用的的工具组合：智能编码辅助和自动控制，支持J2EE，Ant，JUnit和CVS集成，非平行的编码检查和创新的GUI设计器。
4、NetBeans：
NetBeans IDE是一个屡获殊荣的集成开发环境，可以方便的在Windows、Mac、Linux和Solaris中运行。NetBeans包括开源的开发环境和应用平台，NetBeans IDE可以使开发人员利用Java平台能够快速创建Web、企业、桌面以及移动的应用程序。
5、BlueJ：
BlueJ是一款支持Java编程语言的集成开发环境（IDE）。它原本是为了教育目的而开发的，同时也适合于那些想做小型软件开发的开发人员。它的运行需要JDK（Java开发工具包）的帮助。BlueJ主要是为面向对象的程序设计教学而开发的，因此它的设计不同于其他的开发环境。

java网络五子棋
下面的源代码分为4个文件；
chessClient.java:客户端主程序。
chessInterface.java:客户端的界面。
chessPad.java:棋盘的绘制。
chessServer.java:服务器端。
可同时容纳50个人同时在线下棋，聊天。
没有加上详细注释，不过绝对可以运行，j2sdk1.4下通过。

1.其实就是用一个外部程序 调用java虚拟机运行你的java程序。
2.可以做一个批处理文件，在里面调用java 虚拟机运行你的java程序。
3.也可以用某种编程语言，像vb ,c 或c++编个程序，生成exe，能调用java虚拟机运行你的程序，很简单的。
【源代码】
源代码（也称源程序），是指一系列人类可读的计算机语言指令。 在现代程序语言中，源代码可以是以书籍或者磁带的形式出现，但最为常用的格式是文本文件，这种典型格式的目的是为了编译出计算机程序。

Java是一门面向对象编程语言，不仅吸收了C++语言的各种优点，还摒弃了C++里难以理解的多继承、指针等概念，因此Java语言具有功能强大和简单易用两个特征。Java语言作为静态面向对象编程语言的代表，极好地实现了面向对象理论，允许程序员以优雅的思维方式进行复杂的编程。
