Creation and use of thread pool

public ThreadPoolExecutor(int corePoolSize, Number of core threads 
                      int maximumPoolSize,  The maximum number of threads supported by this thread pool 
                      long keepAliveTime,  Specify the time for the thread to survive at zero 
                      TimeUnit unit,  Specify the unit of survival time   second   branch   when   God 
                      BlockingQueue<Runnable> workQueue,  Specify task queue 
                      ThreadFactory threadFactory,  Specify which thread factory to create the thread 
                      RejectedExecutionHandler handler)   The specified thread is busy   When the task is full , What about the new task ？
