用数组和字符串，不使用指针，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，用java实现

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

        // 随机生成1~9的数字填充二维数组
        for (int i = 0; i < magicSquare.length; i++) {
            for (int j = 0; j < magicSquare[i].length; j++) {
                magicSquare[i][j] = (int) (Math.random() * 9 + 1);
            }
        }

        // 输出原始的二维数组
        System.out.println("原始的二维数组：");
        for (int i = 0; i < magicSquare.length; i++) {
            for (int j = 0; j < magicSquare[i].length; j++) {
                System.out.print(magicSquare[i][j] + " ");
            }
            System.out.println();
        }

        // 计算每行、每列、每个对角线的和
        int[] rowSum = new int[3];
        int[] colSum = new int[3];
        int diagonalSum1 = 0;
        int diagonalSum2 = 0;
        for (int i = 0; i < magicSquare.length; i++) {
            for (int j = 0; j < magicSquare[i].length; j++) {
                rowSum[i] += magicSquare[i][j];
                colSum[j] += magicSquare[i][j];
                if (i == j) {
                    diagonalSum1 += magicSquare[i][j];
                }
                if (i + j == 2) {
                    diagonalSum2 += magicSquare[i][j];
                }
            }
        }

        // 判断是否满足条件
        boolean isMagic = true;
        for (int i = 0; i < rowSum.length; i++) {
            if (rowSum[i] != 15 || colSum[i] != 15) {
                isMagic = false;
                break;
            }
        }
        if (diagonalSum1 != 15 || diagonalSum2 != 15) {
            isMagic = false;
        }

        // 输出结果
        if (isMagic) {
            System.out.println("满足条件的二维数组：");
            for (int i = 0; i < magicSquare.length; i++) {
                for (int j = 0; j < magicSquare[i].length; j++) {
                    System.out.print(magicSquare[i][j] + " ");
                }
                System.out.println();
            }
        } else {
            System.out.println("没有满足条件的二维数组。");
        }
    }
}
