8-1 sdut-线程-1 利用多线程类实现20个偶数和20个奇数的随机输出。

public class Number extends Thread {
    int value;

    public Number(int value) {
        this.value = value;
    }

    @Override
    public void run() {
        for(int i = 0; i < 20; i ++)
        {
            System.out.println(value + " ");
            value += 2;
        }
    }
}

public class Main {
    public static void main(String[] args) {
        Number n = new Number(0);
        Number m = new Number(1);
        n.start();
        m.start();
    }
}

class my implements Runnable
{
    int num = 10;

    @Override
    public void run() {
        while(true)
        {
            if(num <= 0)
            {
                break;
            }
            System.out.println(Thread.currentThread().getName()+"卖出第"
            +num--+"张票");
        }
    }

public class Main {
    public static void main(String[] args) {
        my m = new my();
        Thread t1 = new Thread(m, "窗口1");
        Thread t2 = new Thread(m, "窗口2");
        Thread t3 = new Thread(m, "窗口3");
        t1.start();
        t2.start();
        t3.start();

    }
}

class my implements Runnable
{
    @Override
    public void run()
    {
        for(int i = 1; i <= 10; i ++)
            System.out.println(Thread.currentThread().getName()+"卖出第"+i+"票");
    }

        Thread t1 = new Thread(m1, "窗口1");
        Thread t2 = new Thread(m1, "窗口2");
        Thread t3 = new Thread(m1, "窗口3");
        t1.start();
        t2.start();
        t3.start();
    }
