板桥大哥:
我觉得你说得不对, 因为jdk上面这样说的:
Selects a set of keys whose corresponding channels are ready for I/O operations.
This method performs a blocking selection operation. It returns only after at least one channel is selected, this selector's wakeup method is invoked, or the current thread is interrupted, whichever comes first.
况且在你的提到的链接的例子里面, 你也是在做循环, 没有使用sleep或wait()方法的
请您指正!
