首先，你需要安装jdk并配置环境变量。
然后，在命令行中，用javac命令编译你用记事本编写的代码。
下一步，在命令行中，用java命令执行编译后的结果。

1. 新建一个记事本，后缀名是 .java ；然后在里面写一段java的代码，如图：
2.把写好的java文件丢进D盘，就是第一步给出的那个class文件；
3. 打开dos界面 开始-〉运行-〉cmd-〉 这个是命令行模式,选择D盘，如图：
4.选择D盘之后，在命令提示符中输入“javac 文件名.java”,我的文件名为java，所以输入javac java.java然后回车，等待编译。这时候你就会发现它提示说javac不是内部文件。接下来就是java环境变量设置的问题了；
5.下载一个jdk执行默认安装。例如我下的jdk版本是： jdk-6u10-rc2-bin-b32-windows-i586-p-12_sep_2008.exe；
6.配置环境：右击我的电脑点属性，进去点高级就能看到环境变量。点进去就能设置你的系统变量了，如图：
6-1。变量名：classpath 变量值：(.;C:\Program Files\Java\jdk1.6.0_10\lib;)括号里面都是 （主要我们在编译运行程序的时候通过classpath可以帮助我们找到一些需要的系统类，“.”号是表示当前路径；“;”号是用来隔开多个变量值，如果你的系统里面已经有classpath环 境变量，就不用新建了，直接加“;”号，在后面加新值）；如图所示
给你个做好了的Java的源程序的记事本，自己看看就行了的，不怎么难的···
