And how are u storing ur data in the 2D array...?I think single dimensional would be fine

When posting code, please use code tags next time (see: http://forum.java.sun.com/help.jspa?sec=formatting).

public void updateDetails(int[][] IDAndNumber) {

for(int r = 0; r < IDAndNumber.length; r++) {

int[] row = IDAndNumber[r];

// do something with each row

}

If I peer into my crystal ball, I can see hist data structure looks like this:

int[][] array = {

{1, 11},

{2, 22},

{3, 33}

};

where 1,2 and 3 are ID's and 11, 22 and 33 are his numbers.
