特点: 队列中有优先级比较的线程池

使用案例：

val pool: ExecutorService = ThreadPoolExecutor(    3,     3,     0,     TimeUnit.SECONDS,    PriorityBlockingQueue
    
     ())复制代码
    

暂时先用java写着public abstract class PriorityRunnable implements RUnnable, Comparable
    
      {    private int priority;        public PriorityRunnable(int priority) {        if (priority < 0) {            throw new IllegalArgumentException();        }        this.priority = priority;    }        public int getPriority() {        return priority;    }        @Override    public int compareTo(@NonNull PriorityRUnnable another) {        int me = this.priority;        int anotherPri = another.getPriority();        return me == anotherPri ? 0 : me < anotherPri ? 1 : -1;    }        @override    public void run() {        doSomeThing();    }        protected abstract void doSomeThing();}复制代码
    

txt.click {    for (i in 0..99) {        val priority = i        pool.execute(object: PriorityRunnable(priority) {            override doSomeThing() {                log("优先级${proiority}的任务被执行")                try {                    Thread.sleep(2000)                }catch (e: Exception) {                    e.printStackTrace()                }            }        })    }}复制代码
