| 例，客户端输入商品价格，在服务器端负责游戏逻辑的处理。
服务器端代码:
Guess.jsp 这个文件放到d:/ mygameWeb目录下面
＜%
String sjg=request.getParameter("jg");
int jg=(int)(Math.random()*10);
int userjg=Integer.parseInt(sjg);
if(userjg>jg)
{
out.println("sorry da le");
}
if(userjg＜jg)
{
out.println("sorry xiao le");
}
if(userjg==jg)
{
out.println("right");
}
%>
J2me客户端代码:
