java随机生成双色球幸运号码

以下是Java随机生成双色球幸运号码的代码示例：

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

public class DoubleColorBall {
    public static void main(String[] args) {
        int[] redBalls = new int[33];
        for (int i = 0; i < redBalls.length; i++) {
            redBalls[i] = i + 1;
        }
        int[] selectedRedBalls = new int[6];
        Random random = new Random();
        for (int i = 0; i < selectedRedBalls.length; i++) {
            int index = random.nextInt(redBalls.length - i);
            selectedRedBalls[i] = redBalls[index];
            redBalls[index] = redBalls[redBalls.length - i - 1];
        }
        Arrays.sort(selectedRedBalls);
        int selectedBlueBall = random.nextInt(16) + 1;
        System.out.println("红球：" + Arrays.toString(selectedRedBalls));
        System.out.println("蓝球：" + selectedBlueBall);
    }
}
