//構造器1 public ThreadPoolExecutor(int corePoolSize,int maximumPoolSize,long keepAliveTime,TimeUnit unit,BlockingQueue<Runnable> workQueue) {this(corePoolSize, maximumPoolSize, keepAliveTime, unit, workQueue,Executors.defaultThreadFactory(), defaultHandler); } //構造器2 public ThreadPoolExecutor(int corePoolSize,int maximumPoolSize,long keepAliveTime,TimeUnit unit,BlockingQueue<Runnable> workQueue,RejectedExecutionHandler handler) {this(corePoolSize, maximumPoolSize, keepAliveTime, unit, workQueue,Executors.defaultThreadFactory(), handler); } //構造器3 public ThreadPoolExecutor(int corePoolSize, int maximumPoolSize,long keepAliveTime, TimeUnit unit, BlockingQueue<Runnable> workQueue, ThreadFactory threadFactory, RejectedExecutionHandler handler);構造器參數詳解如下： corePoolSize：核心線程的數量； maximumPoolSize：最大的線程數量； keepAliveTime：當線程數量大于corePoolSize時，多余的線程的最大存活時間（如果空閑的話）； unit：keepAliveTime的單位； workQueue：提交但尚未被執行的任務隊列； threadFactory：線程工廠，用于創建線程； handler：拒絕策略，當任務提交不能被執行時的補救措施；
