public class ThreadDemo extends Thread{
    public int i=0;
    public ThreadDemo(){

        System.out.println("New Thread:"+this.getName());
    }
    public void run(){
        while(true){
            try {
                Thread.sleep(3000);
                this.i ++;
                if(this.i==5){
                    Thread.currentThread().stop();
                }
            } catch (InterruptedException ex) {
            }
            //currentThread() 返回对当前正在执行的线程对象的引用。
            System.out.println(Thread.currentThread().getName()+" is running!   i:"+this.i);
            System.out.println("activeCount"+Thread.activeCount());
        }
    }
