you use bufferedreader read each line , split line using .split(','); method.

some pseudo code:

bufferedreader bfr = new bufferedreader(inputstreamreader/filereader...); string line = null; int index = 0; string [][] xyz = new string [100][5];  while ( (line = bfr.readline()) != null) {     if (index < xyz.length) xyz[index] = line.split(",");     index++; }    

hope helped!
