用java利用随机1~9整数生成3*3的二维数组,使二维数组每行,每列、以及斜线上的数字之和均为15,并输出这个二维数组

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

public class MagicSquare {
    public static void main(String[] args) {
        int[][] magicSquare = new int[3][3];
        Random random = new Random();

        // 随机生成1~9的数字
        int[] numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9};

        // 打乱数字顺序
        for (int i = 0; i < 9; i++) {
            int j = random.nextInt(9);
            int temp = numbers[i];
            numbers[i] = numbers[j];
            numbers[j] = temp;
        }

        // 填充二维数组
        int index = 0;
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 3; j++) {
                magicSquare[i][j] = numbers[index++];
            }
        }

        // 计算每行、每列、每个斜线的和
        int[] rowSum = new int[3];
        int[] colSum = new int[3];
        int[] diagonalSum = new int[2];
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 3; j++) {
                rowSum[i] += magicSquare[i][j];
                colSum[j] += magicSquare[i][j];
                if (i == j) {
                    diagonalSum[0] += magicSquare[i][j];
                }
                if (i + j == 2) {
                    diagonalSum[1] += magicSquare[i][j];
                }
            }
        }

        // 判断是否符合要求
        boolean isMagicSquare = true;
        for (int i = 0; i < 3; i++) {
            if (rowSum[i] != 15 || colSum[i] != 15) {
                isMagicSquare = false;
                break;
            }
        }
        if (diagonalSum[0] != 15 || diagonalSum[1] != 15) {
            isMagicSquare = false;
        }

        // 输出结果
        if (isMagicSquare) {
            for (int[] row : magicSquare) {
                System.out.println(Arrays.toString(row));
            }
        } else {
            System.out.println("无法生成符合要求的3*3幻方。");
        }
    }
}
