(新手)请教这个线程的错误在哪?

Question

ThreadPseudoIO pseudo = new ThreadPseudoIO();
ThreadPseudoIO 不是一个静态内部类。
使用：WithThread.ThreadPseudoIO pseudo = new WithThread.ThreadPseudoIO(); 试试看

Answer 1

在静态函数中不能使用非静态变量.
将ThreadPseudoIO pseudo = new ThreadPseudoIO();
改成
static ThreadPseudoIO pseudo = new ThreadPseudoIO();

Answer 2

应该把class ThreadPseudoIO extends Thread
改成 static class ThreadPseudoIO extends Thread
试试看！
