title: How to store co-ordinates using a two dimensional array?
body: <p>I am doing a project involving a two dimensional array. The project involves a dot that moves from the top left corner to the bottom right corner. What I am doing right now is making an array of possibleXMoves and an array of possibleYMoves. I was wondering if there was a better way to define coordinates for a two dimensional array. Below is what I have.</p>
  
  <pre><code>int moveX1 = x + 1;
      int moveX2 = x + 1;
      int moveX3 = x + 1;
      int moveX4 = x;
      int moveX5 = x - 1;
      int moveX6 = x - 1;
      int moveX7 = x - 1;
      int moveX8 = x;
      int [] possibleXIndexes = {moveX1, moveX2, moveX3, moveX4, moveX5, moveX6, moveX7, moveX8};
  
      int moveY1 = y - 1;
      int moveY2 = y;
      int moveY3 = y + 1;
      int moveY4 = y + 1;
      int moveY5 = y + 1;
      int moveY6 = y;
      int moveY7 = y - 1;
      int moveY8 = y - 1;
      int [] possibleYIndexes = {moveY1, moveY2, moveY3, moveY4, moveY5, moveY6, moveY7, moveY8};
