核心线程空闲时，其状态分为以下两种情况：

- **设置了核心线程的存活时间** ：核心线程在空闲时，会处于阻塞状态，等待获取任务。如果阻塞等待的时间超过了核心线程存活时间，则该线程会退出工作，之后将该线程从线程池的工作线程集合中移除。
- **没有设置核心线程的存活时间** ：核心线程在空闲时，会一直处于阻塞状态，等待获取任务。
- **设置了核心线程的存活时间** ：核心线程在空闲时，会处于 `WAITING` 状态，等待获取任务。如果阻塞等待的时间超过了核心线程存活时间，则该线程会退出工作，将该线程从线程池的工作线程集合中移除，线程状态变为 `TERMINATED` 状态。
- **没有设置核心线程的存活时间** ：核心线程在空闲时，会处于 `WAITING` 状态，等待获取任务。

当核心线程获取任务之后，会由 `WAITING` 状态变为 `RUNNABLE` 状态，之后去执行对应任务。
