用java代码写一个机选双色球

import java.util.Arrays; import java.util.Random;

public class RandomDoubleColorBall { public static void main(String[] args) { int[] redBalls = new int[33]; // 红球范围 1~33 for (int i = 0; i < redBalls.length; i++) { redBalls[i] = i + 1; }

    int[] blueBalls = new int[16]; // 蓝球范围 1~16
    for (int i = 0; i < blueBalls.length; i++) {
        blueBalls[i] = i + 1;
    }

    int[] selectedRedBalls = new int[6]; // 选中的红球
    for (int i = 0; i < selectedRedBalls.length; i++) {
        int index = new Random().nextInt(redBalls.length - i);
        selectedRedBalls[i] = redBalls[index];
        redBalls[index] = redBalls[redBalls.length - 1 - i];
    }

    int selectedBlueBall = blueBalls[new Random().nextInt(blueBalls.length)]; // 选中的蓝球

    Arrays.sort(selectedRedBalls); // 对红球进行排序

    System.out.print("红球：");
    for (int redBall : selectedRedBalls) {
        System.out.print(redBall + " ");
    }
    System.out.println("蓝球：" + selectedBlueBall);
}

}
