java彩虹数字雨源码

以下是Java实现的彩虹数字雨源码：

import java.util.Random;
import java.util.Scanner;

public class RainbowRain {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.print("请输入下落的数字个数：");
        int numCount = sc.nextInt();
        sc.close();

        Random random = new Random();
        for (int i = 0; i < numCount; i++) {
            int num = random.nextInt(10);
            System.out.print("\033[38;5;" + (num + 160) + "m" + num + " ");
            // 0-9 对应的颜色编号为 160-169
        }
    }
}

运行效果如下：
