一、三个构造方法
ThreadPoolExecutor(int corePoolSize,int MaxmumPoolSize,long KeepAliveTime,,TimeUnit unit,BolokingQueue<Runnable> workQueue)
ThreadPoolExecutor(int corePoolSize,int MaxmumPoolSize,long KeepAliveTime,,TimeUnit unit,BolokingQueue<Runnable> workQueue,RejectExceptionHandler handler)
ThreadPoolExecutor(int corePoolSize,int MaxmumPoolSize,long KeepAliveTime,,TimeUnit unit,BolokingQueue<Runnable> workQueue,ThreadFactory threadFactory)
ThreadPoolExecutor(int corePoolSize,int MaxmumPoolSize,long KeepAliveTime,,TimeUnit unit,BolokingQueue<Runnable> workQueue,ThreadFactory threadFactory,RejecExceptiontHandler handler,)
标注
1、CorePoolSize 线程池的基本大小
2、MaxmunPoolSize 线程池最大数量
3、KeepAliveTime 线程活动保持时间
4、BlokingQueue 任务队列 （ArrayBlokingQueue LinkedBlokingQueue synchronousQueue PriorityBlokingQueue）
5、RejectExceptionHandler 饱和策略 （AbortPlicy CallerRunsPolicy DiscardOldestPolicy DiscardPolicy）
6、ThreadFactory
