线程使用

 class Hi implements Runnable {
    int times= 0;
    @Override
    public void run() {
        while (true){
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println("hi"+(++times));
            if (times == 10){
                break;
            }
        }
    }
    public static void main(String[] args) {
        Hi hi = new Hi();
        //创建thread对象
        Thread thread = new Thread(hi);
        thread.start();
    }
}

线程的终止

public class Exit {
    public static void main(String[] args) {
        T t = new T();
        t.start();
        try {
            System.out.println("休眠5s...");
            Thread.sleep(10*500);
            t.setLoop(false);//设置loop的值
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
class T extends Thread{
    private int count = 0;
    //设置一个boolean 类型的对象，后面好赋值条件
    private  Boolean loop = true;
    //提供set方法给loop赋值
    public void setLoop(Boolean loop) {
        this.loop = loop;
    }
    @Override
    public void run() {
      while (loop){
          System.out.println("T 运行中....");
          try {
              Thread.sleep(100);
          } catch (InterruptedException e) {
              e.printStackTrace();
          }
      }
    }
}
