I have a file with data in the form timestamp, coordinate, coordinate, seperated by spaces, as here;

14:25:01.215 370.0 333.0

I need to loop through and add the coordinates only to an array. The data from the file is read in and put into as String[] called info, from split(" "). I have two problems, I think the end of the file has a extra " " which I need to lose appropriately and I also want confirmation/suggestions of my loop, at the moment I am getting sporadic out of bounds exceptions. My loop is as follows;

String[] info;
info = dataHolder.split(" ");
ArrayList<String> coOrds1 = new ArrayList<String>();
for (int counter = 0; counter < info.length; counter = counter+3)
{
    coOrds1.add(info[counter+1]);
    coOrds1.add(info[counter+2]);
}

Help and suggestions appreciated.

The text file is here but the class receives in a UDP packet from another class so I am unsure if this potentially adds " " at the end or not.
