使用继承Thread类的方式创建线程

银行叫号部分的代码

package com.dwz.concurrency.chapter2;
/**
 *    使用static保证号码数据共享
 *    线程的创建方式：继承Thread类
 */
public class TicketWindow extends Thread{
    private static final int MAX = 100;
    //号码
    private static int index = 1;
    private final String name;

    public TicketWindow(String name) {
        this.name = name;
    }

    @Override
    public void run() {
        while(index <= MAX) {
            System.out.println(name + "当前的号码是：" + (index++));
        }
    }
}

测试代码：

package com.dwz.concurrency.chapter2;

public class Bank {
    public static void main(String[] args) {
        TicketWindow tw = new TicketWindow("一号柜台");
        tw.start();

        TicketWindow tw2 = new TicketWindow("二号柜台");
        tw2.start();

        TicketWindow tw3 = new TicketWindow("三号柜台");
        tw3.start();
    }
}

使用实现Runnable接口的方式创建线程

银行叫号部分的代码

package com.dwz.concurrency.chapter2;
/**
 * 实现业务逻辑和线程的分离
 */
public class TicketWindowRunnable implements Runnable {
    private static final int MAX = 100000;
    private int index = 1;

    public void run() {
        while(index <= MAX) {
            System.out.println(Thread.currentThread().getName() + " 的号码是：" + (index++));
        }
    }
}

测试代码：

package com.dwz.concurrency.chapter2;
/**
 * 此方式可以保证TicketWindowRunnable类被实例化一次
 * 三个线程共用一个TicketWindowRunnable对象，达到共享号码的目的
 */
public class BankVersion2 {
    public static void main(String[] args) {
        TicketWindowRunnable wr = new TicketWindowRunnable();
        Thread thread1 = new Thread(wr, "柜台一");
        Thread thread2 = new Thread(wr, "柜台二");
        Thread thread3 = new Thread(wr, "柜台三");

        thread1.start();
        thread2.start();
        thread3.start();
    }
}
