java - Best way to move around a 2d Array (Board Game) -

i curious easiest way move around 2d array in java? created 2d array game board , use keep track of positions of game pieces. if have 16x16 2d array how make players can move around board x number of spaces.

i know pieces move from:

[0][0] -> [0][16] - top

then

[0][16] -> [16][16] - right side

then

[16][16] -> [16][0] - bottom

then home space being [0][0].

[16][0] -> [0][0] - left side

any or suggestions appreciated!

edit: wish accept multiple correct answers.... sigh ;(

based on comment, implement restriction on movement following pseudocode. i'm not 100% sure if want, it's helpful

if (user tries move right) {     if (posx < 15 && posy == 0)          //move right     else          //don't }  if (user tries move left) {     if (posx > 0 && posy == 15)          //move left     else          //don't } 

and on. similar you're looking for? restrictions on array traversal? i'm assuming board allows movement on boundaries of array based on say, following o positions legal, , x illegal:

ooooooooooooooo oxxxxxxxxxxxxxo oxxxxxxxxxxxxxo ... oxxxxxxxxxxxxxo ooooooooooooooo
