初学者遇到了小疑点 关于List的， 求教
菜鸟遇到了小问题 关于List的， 求教
------解决方案--------------------
你那个clients没有声明呀，那来的？ChatSever和Client是两个不同的类呀！
------解决方案--------------------
你的不是内部类。吧 }
class Client implements Runnable{
}
上的}移到最下面就好了 这就是内部类了。
什么逻辑。一个客户端发来请求，要响应所有的客服端啊。。。
------解决方案--------------------
绝对不是内部类,
你将客户端类剪切掉,没有报错,说明你定义在了服务器端类外面,所以引用会失败
