线程池有哪些状态？

线程池的5种状态：RUNNING、SHUTDOWN、STOP、TIDYING、TERMINATED。

见 ThreadPoolExecutor 源码

// runState is stored in the high-order bits
    private static final int RUNNING    = -1 << COUNT_BITS;
    private static final int SHUTDOWN   =  0 << COUNT_BITS;
    private static final int STOP       =  1 << COUNT_BITS;
    private static final int TIDYING    =  2 << COUNT_BITS;
    private static final int TERMINATED =  3 << COUNT_BITS;
