请教java调用cmd
请教JAVA调用cmd问题：
1.在java中调用cmd
process = Runtime.getRuntime().exec("cmd");
2.取得cmd的输出：
Microsoft Windows XP [版本 5.1.2600]
(C) 版权所有 1985-2001 Microsoft Corp.
E:\WORK\workplace\
此时CMD未关闭。
3。向cmd传送命令，并取得结果。
例如 传送 DIR，取得结果
2009-06-11 12:18 <DIR> .
2009-06-11 12:18 <DIR> ..
2009-06-09 15:25 377 .classpath
2009-06-09 15:19 385 .project
2009-06-11 11:58 <DIR> .settings
2009-06-11 12:43 <DIR> bin
2009-06-11 11:58 <DIR> src
2 个文件 762 字节
5 个目录 35,043,749,888 可用字节
4向cmd传送EXIT，cmd关闭
请问如何实现？
