解决不了我会死不瞑目！！！！

class Pro implements Runnable
{
private Resource res;
public Pro(Resource res)
{
this.res = res;
}
public void run ()
{
while (true)
{
res.add("馒头");
}
}

}

class Con implements Runnable
{
private Resource res;
public Con(Resource res)
{
this.res = res;
}
public void run ()
{
while (true)
{
res.get();
}
}

}
运行出错，不知道什么原因。

------解决方案--------------------
把Con类名换掉，Con是系统关键字不能使用
