Actor是否實現了Runable或繼承了Thread，run方法是否有問題

查看下 Actor類 是否實現了 runable接口
舉報
帶你一起深入淺出多線程，掌握基礎，展望進階路線
3 回答Thread actor=new Actor(); 這怎么理解?
2 回答new Thread
4 回答Thread actressThread = new Thread(new Actress(),"Ms. Runnable");
1 回答Thread actressthread=new Thread(new Actress(),"Ms.Runnable");報錯啊
2 回答new一個Actor類的對象賦給Thread類型的引用和賦給Actor類型的引用，效果是一樣的
