}
public void talk(InputS
private void reply(PrintWriter out,String question)throws Exception
{Thread.sleep((int)Math.random()*1000);
out.println(name+":"+question); //这句要改
}
改为System.out.println(name+":"+question);
运行结果:
jian:Hello!!
chen:Hello!!
注意,println是System.out里的方法,如果没有了System那系统就不知如何去找到out.println()了,System.out是标准输出.可能是你的大意,以后可以注意一下就好了!呵呵.
帮你测试了下，没有什么大的错误
呵呵，就是一个小错误，你没有发现
就是最后一行代码
out.println(name+":"+question);
这个改成System.out.println(...);
---------- 运行 ----------
chen:Hello!!
jian:Hello!!
这个就是结果,你可以试试看哦
