经典进程问题：5个窗口卖100张票，卖完为止。用Runnable和Thread2种方法实现

import java.util.Random;
public class TicketThread  extends Thread{
  private static   int i=1;
  Thread th =Thread.currentThread();
  String name;
  public TicketThread(String name) {
    super();
    this.name = name;
  }
  public  void run() {
 while(i<=96) {
           try {
      th.sleep(new Random().nextInt(1000));
    } catch (InterruptedException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }     
           synchronized(this) {
             System.out.println(this.name+",出售第"+i+"张票");
            i++;
           }
 }       
  }
}

public class TestThread {
  public static void main(String[] args) {
    TicketThread th1 = new TicketThread("窗口1");
    TicketThread th2 = new TicketThread("窗口2");
    TicketThread th3 = new TicketThread("窗口3");
    TicketThread th4 = new TicketThread("窗口4");
    TicketThread th5 = new TicketThread("窗口5");
    th1.start();
    th2.start();
    th3.start();
    th4.start();
    th5.start();
  }
}

public class TicketRunnable implements Runnable {
  Thread th = Thread.currentThread();
  int i = 1;
  public void run() {
    while (i <= 96) {
      try {
        th.sleep(50);
      } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      }
      synchronized (this) {
        System.out.println(Thread.currentThread().getName() + ",出售第" + i + "张票");
        i++;
      }
    }
  }
}

public class TestRunnable {
  public static void main(String[] args) {
    TicketRunnable  tr =new TicketRunnable();
    Thread th1 = new Thread(tr,"窗口1");
    Thread th2 = new Thread(tr,"窗口2");
    Thread th3 = new Thread(tr,"窗口3");
    Thread th4 = new Thread(tr,"窗口4");
    Thread th5 = new Thread(tr,"窗口5");
    th1.start();
    th2.start();
    th3.start();
    th4.start();
    th5.start();
  }
}
