遍历2D数组

Question

I need to create a method that will take a specific index in a 2D array and print out the values of the neighboring cells in clockwise order. I am not sure if I have to hardcode this program with a bunch of "If" statements or is there a looping way to achieve it?

The method takes in two parameters (rows and columns) and returns a String giving the values with a comma in between.

I'm guessing you want something like this (constructor etc. omitted):

public class weird_array_class_of_doom{

    public array[][] the_thing;

    public void print_the_cells(int row, int col){
        System.out.print(array[row][col+1];
        System.out.print(array[row+1][col];
        System.out.print(array[row][col-1];
        System.out.print(array[row-1][col];
    }
}
