在3和4还能运行 大家可以用telnet测试 为什么呀 请各位帮忙 解决马上给分

[hpym365]

没人帮忙吗？？？？
public String getMessage()
{
while(rlist.size()<=0)
{
try
{
wait();
}
catch(Exception ex){}
System.out.println("*********3");
}
return rlist.removeFirst();
}


public String getMessage()
{
while(slist.size()<=0)
{
try
{
wait(); //为什么wait了 现成还在运行？？？
}
catch(Exception ex){}
System.out.println("*********4");
}
return slist.removeFirst();
}

大概就是这两个位置的问题 线程wait()了 但是不停止还继续运行

帮你看看
别急

[shenjialong2008]

wait()怎么没放在synchronized里面！
