编写一个应用程序创建两个线路，一个线程打印输出1~1000之间所有的奇数，另外一个线程打印输出1~1000之间所有的偶数，要求两个线程随机休眠一段时间后（1秒内）继续打印输出下一个数。分别用Runnable接口和Tread类编程实验。

使用Runnable接口：

public class NumberPrinter implements Runnable {
    private int start;
    private int end;
    private int increment;

    public NumberPrinter(int start, int end, int increment) {
        this.start = start;
        this.end = end;
        this.increment = increment;
    }

    @Override
    public void run() {
        for (int i = start; i <= end; i += increment) {
            System.out.println(i);
            try {
                Thread.sleep((long) (Math.random() * 1000));
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

public class Main {
    public static void main(String[] args) {
        Thread oddThread = new Thread(new NumberPrinter(1, 1000, 2));
        Thread evenThread = new Thread(new NumberPrinter(2, 1000, 2));
        oddThread.start();
        evenThread.start();
    }
}

使用Thread类：

public class NumberPrinter extends Thread {
    private int start;
    private int end;
    private int increment;

    public NumberPrinter(String name, int start, int end, int increment) {
        super(name);
        this.start = start;
        this.end = end;
        this.increment = increment;
    }

    @Override
    public void run() {
        for (int i = start; i <= end; i += increment) {
            System.out.println(i);
            try {
                Thread.sleep((long) (Math.random() * 1000));
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

public class Main {
    public static void main(String[] args) {
        Thread oddThread = new NumberPrinter("OddThread", 1, 1000, 2);
        Thread evenThread = new NumberPrinter("EvenThread", 2, 1000, 2);
        oddThread.start();
        evenThread.start();
    }
}
