java - Java中线程的空闲时间是什么意思？

Question

Java 中线程的空闲时间是什么意思？我正在阅读Java The Complete Reference 8th edition's和它说的是这样的:

...One thread can pause without stopping other parts of your program. For example, the idle time created when a thread reads data from a network or waits for user input can be utilized elsewhere...

Answer 1

在这种情况下，这意味着线程的状态是 WAITING或TIMED_WAITING ，这意味着

A thread in the waiting state is waiting for another thread to perform a particular action.
