java实现Runnable接口适合资源的共享

public class ThreadDemo {
  public static void main(String[] args) {
    HelloThread t1 = new HelloThread();
    t1.setName("一号窗口");
    t1.start();
    HelloThread t2 = new HelloThread();
    t2.setName("二号窗口");
    t2.start();
  }

}
class HelloThread extends Thread{

   private int ticket = 5;
  public void run() {
    while(true){
      System.out.println(this.getName()+(ticket--));
      if (ticket<1) {
        break;  
      }
    }
  }

}

public class ThreadDemo {
  public static void main(String[] args) {
    HelloThread t = new HelloThread();
    Thread thread1 = new Thread(t, "1号窗口");
    thread1.start();
    Thread thread2 = new Thread(t, "2号窗口");
    thread2.start();
  }

}
class HelloThread implements Runnable{

  private int ticket = 5;
  public void run() {
    while(true){
      System.out.println(Thread.currentThread().getName()+(ticket--));
      if (ticket<1) {
        break;  
      }
    }
  }

}
