How to print 2D Array from .txt file in Java -

import java.io.bufferedreader; import java.io.file; import java.io.filereader; import java.io.ioexception; import java.util.stringtokenizer;   public class csvimport5 {       public static void main(string[] args) throws ioexception {           double [][] data = new double [87][2];           file file = new file("buydata.txt");         int row = 0;         int col = 0;         bufferedreader bufrdr  = new bufferedreader(new filereader(file));         string line = null;           //read each line of text file         while((line = bufrdr.readline()) != null && row < data.length)         {            stringtokenizer st = new stringtokenizer(line,",");         while (st.hasmoretokens())         {             //get next token , store in array             data[row][col] = double.parsedouble(st.nexttoken());             col++;         }         col = 0;         row++;         }          system.out.println(" "+data[87][2]);              }      } 

error message:

arrayindexoutofbounds exception @ "system.out.println(" "+data[87][2]); 

my txt file is:

8.00,28.00   18.00,28.00  8.00,23.00   12.00,20.00  15.00,30.00  12.00,32.00  12.00,20.00  18.00,31.00  29.00,25.00  6.00,28.00   7.00,28.00   6.00,24.00 14.00,30.00  11.00,23.00  12.00,20.00  31.00,24.00  11.00,20.00  17.00,23.00  14.00,32.00  15.00,23.00  8.00,20.00   17.00,31.00  7.00,20.00 12.00,23.00  15.00,20.00  12.00,20.00  21.00,20.00  27.00,27.00  18.00,20.00  25.00,27.00  46.00,13.00 26.00,10.00  47.00,22.00  44.00,14.00 34.00,4.00 34.00,4.00   44.00,7.00   39.00,5.00   20.00,0.00   43.00,11.00  43.00,25.00  34.00,2.00   25.00,10.00  50.00,9.00   25.00,9.00   39.00,2.00   34.00,7.00   44.00,15.00  36.00,3.00   40.00,5.00   49.00,21.00  42.00,7.00   35.00,1.00   30.00,2.00   31.00,13.00  53.00,12.00  40.00,4.00   26.00,4.00   50.00,55.00 57.00,51.00  62.00,52.00  56.00,52.00  59.00,40.00  61.00,68.00  66.00,49.00  57.00,49.00 62.00,58.00  47.00,58.00  53.00,40.00  60.00,54.00  55.00,48.00  56.00,65.00  67.00,56.00  55.00,43.00  52.00,49.00  67.00,62.00 68.00,61.00  65.00,58.00  46.00,53.00  46.00,49.00  47.00,40.00  64.00,22.00  64.00,54.00  63.00,64.00  63.00,56.00  64.00,44.00  63.00,40.00 

double [][] data = new double [87][2]; create double[][] size 87 , 2.

the index reference these entries 86 , 1 (an array starts index "0" , not "1")

try:

 system.out.println(" "+data[86][1]);       

that should work!
