Changing A JButton's Icon In an Array of JButtons

Question

I am making a battleship game and I have an array of buttons set up on the playing board.
When the user clicks a button, if it is a hit I would like the icon of the button to change.
This is what I have so far...
playerOcean = m1.getplayerOcean();
     compOcean = m1.getpcOcean();
          for (int x=0; x < 10; x++)
               for (int y=0; y < 10; y++)
                    if (playerOcean[x][y] == 2)
                         playButtons [x] [y].setIcon(hit);
Where hit = private Icon hit = new ImageIcon("boom.jpg");
And playerOcean is the array in which the locations of the ships are stored, where 2 is a hit.

Hi, mygrymm-
There are lots of inefficient ways to do this having to do with traversing arrays, etc., but probably the best thing for you to do is to create a two dimensional associative array, or an Object of Objects, in JavaScript parlance.  That way, you can look up the X in the parent object and the Y in that object to see if it exists.  Here's a really brief sample that I haven't tested, but should get you going in the right direction.
Let's say my boundary is 4, 5:
var xArray = new Object();
xArray["4"] = new Object();
xArray["4"]["5"] = true;
Then, when I test....
var currX = somehow.get.the.object.x.value;
var currY = somehow.get.the.object.y.value;
if (xArray[currX.toString()][currY.toString()] == true) {
   console.log("boundary hit!");
Hope that helps,
