在Java中检查二维数组中的邻居的更有效方法

public class NeighborChecker {
    public static void main(String[] args) {
        int[][] array = {
            {1, 2, 3},
            {4, 5, 6},
            {7, 8, 9}
        };

        int row = 1;
        int col = 1;

        int[] dx = {-1, 0, 1, 0}; // 横向相邻元素的偏移量
        int[] dy = {0, -1, 0, 1}; // 纵向相邻元素的偏移量

        for (int i = 0; i < 4; i++) {
            int newRow = row + dx[i];
            int newCol = col + dy[i];

            if (newRow >= 0 && newRow < array.length && newCol >= 0 && newCol < array[0].length) {
                int neighbor = array[newRow][newCol];
                System.out.println("邻居元素: " + neighbor);
            }
        }
    }
}
