I have a problem writing a Java Method.

That’s the situation:
There is a Matrix (number of rows and cols will be given via scanner). In this Matrix every point is a Rock. Now we exchange one random Rock with a bottle of Coke with some Mentos in it and we want to find out which rock will get wet.

The Parameter:

1. Every Rock gets wet as long as it is not hidden behind another Rock in vertical, diagonal or horizontal direction. For example:

(D = Dry, W = Wet Rock, B = Bottle)

• 0 1 2 3
  0 W W W W
  1 W B W D
  2 W W W W
  3 W D W D

Now, how do I implement the isWet() method?
