changing spots on a 2-d array (ready to program java 1.7.1)

[Jmack]

I'm creating a RTP java version of battleship. everything in the game is finished except for the last thing that is needed which is a way to update the player and AI board after a person shoots at a spot. basically the board is made up of 0's as just plain water an di want them to be able to change to either *=shot but no hit or X = shot and hit.


this is the code for the 2d array
for (int i = 0 ; i < field.length ; i++)
{
int[] sub = field [i];
for (int x = 0 ; x < sub.length ; x++)
{
c.print (sub [x] + " ");
}
c.println ();
}

and her is version of the game so far
