Answer 1

// 生成矩阵行数
        int x = 5;
        // 生成矩阵列数
        int y = 4;
        int range = 100;
        Random random = new Random();
        int[] max = {0, 0, 0};
        int[] min = {range, 0, 0};
        for (int a = 0; a < x; a++){
            for (int b = 0; b < y; b++){
                int i = random.nextInt(range);
                System.out.print(i + " ");
                if (i > max[0]){
                    max[0] = i;
                    max[1] = a + 1;
                    max[2] = b + 1;
                }
                if (i < min[0]){
                    min[0] = i;
                    min[1] = a + 1;
                    min[2] = b + 1;
                }
            }
            System.out.println();
        }
        System.out.println("最大值及X，Y坐标分别为：" + Arrays.toString(max));
        System.out.println("最小值及X，Y坐标分别为：" + Arrays.toString(min));
