运行这段程序将会得到下面的结果：
SSClient创建了一个Socket对象与运行在主机端口10000的服务程序联系，主机的IP地址由host变量确定。SSClient将获得Socket的输入输出流，围绕BufferedReader的输入流和PrintWriter的输出流对字符串进行读写操作就变得非常容易，SSClient个服务程序发出各种date/time命令并得到响应，每个响应均被打印，一旦最后一个响应被打印，将执行Try/Catch/Finally结构的Finally子串，Finally子串将在关闭Socket之前关闭BufferedReader 和 PrintWriter。 在SSClient源代码编译完成后，可以输入java SSClient 来执行这段程序，如果有合适的程序运行在不同的主机上 |
