Q3: 用java程序来做限速,下载文件的代码修改
用java程序来做限速，方向就有问题，如果大并发量，都要控制速度你程序早就挂了。应该用应用服务器（我想你用的tomcat吧）+http服务器控制，这里用apache就可以了。用apache来做限速才是正确的，用程序代码几乎是没法限速，http 协议是无状态的协议。
当然你一定要做， 那就是写一定数量流，拿这个数据流的大小与你限速的平均量比，如果超过了就程序暂停一会。（这样设计很不合理，但可以达到你的要求）
还有两个,快了
Q4: 用Java语言实现空调的风速的控制代码怎么写？
/**
*@param i 调档
*1.低档 2.中档 3.高档
*/
public void test（int i）{
switch (i) {
case 1:
syso（“低档”）；
break;
case 2:
syso（“中档”）；
break;
case 3:
syso（“高档”）；
break;
default:
break;
}
}
应该就是这样吧
