多线程实现奇偶数的依次输出

话不多说直接上代码：

package 多线程;

public class Test13_多线程实现奇偶数依次输出 {
    public static void main(String[] args) {

        //创建共享数据对象
        Num num = new Num(1);

        //创建线程对象，两个线程都共享Num数据
        Thread t1 = new Thread(new PrintOdd(num));
        t1.setName("奇数");
        Thread t2 = new Thread(new PrintEven(num));
        t2.setName("偶数");

        //启动线程、
        t1.start();
        t2.start();

    }
}



//共享数据
class Num{
    int count;//共享
    public Num(int count){
        this.count = count;
    }
    //对外提供打印奇数的方法
    public void printOdd() throws InterruptedException {
        synchronized(this){
            System.out.println(Thread.currentThread().getName()+"--->"+count++);
            Thread.sleep(1000);
            this.notifyAll();
            this.wait();
        }
    }
    //对外提供打印偶数的方法
    public void printEven() throws InterruptedException {
        synchronized(this){
            System.out.println(Thread.currentThread().getName()+"--->"+count++);
            Thread.sleep(1000);
            this.notifyAll();
            this.wait();
        }
    }

}


//线程1
class PrintOdd implements Runnable{
    Num num;
    //构造
    public PrintOdd(Num num){
        this.num = num;
    }

    //run方法打印奇数
    public void run() {
        while(true){
            try {
                num.printOdd();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}
//线程2
class PrintEven implements  Runnable{
    Num num;
    public PrintEven(Num num){
        this.num = num;
    }
    //run方法打印偶数
    public void run() {
        while(true){
            try {
                num.printEven();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

运行结果：
