一 多线程、并发、锁
- 线程的生命周期，状态是如何转移的
- NEW:A thread that has not yet started is in this state.
- RUNABLE: A thread executing in the Java virtual machine is in this state.
- BLOCKED: A thread that is blocked waiting for a monitor lock is in this state.
- WAITING : A thread that is waiting indefinitely for another thread to
perform a particular action is in this state.
- TIME WAITING : A thread that is waiting for another thread to perform an action
for up to a specified waiting time is in this state.
- TERMINATED : A thread that has exited is in this state.
- 线程池的实现原理？
- 线程池中的coreNum和maxNum有什么不同？
