使用newSingleThreadExecutor()創建靜態線程池

    public static void main(String[] args) {
        //始終只有一個線程在執行
        //使用newSingleThreadExecutor()創建靜態線程池
        ExecutorService SinglePool = Executors.newSingleThreadExecutor();
        for (int i = 0; i < 10; i++) {
            SinglePool.execute(new MyThead02(i));
        }
    }
}
class MyThead02 implements Runnable{
    int num;

    public MyThead02(int num) {
        super();
        this.num = num;
    }
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName()+":"+num);    
    }
