二维数组的邻接值(java)

public class AdjacentValues {

        int[][] array = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
        int rows = array.length;
        int cols = array[0].length;

        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < cols; j++) {
                int value = array[i][j];
                System.out.print("Element: " + value + ", Adjacent Values: ");

                // 上方元素
                if (i > 0) {
                    System.out.print(array[i - 1][j] + " ");
                }
