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 = 87;     int col = 2;     bufferedreader bufrdr  = new bufferedreader(new filereader(file));     string line ;       //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[col][row] = double.parsedouble(st.nexttoken());         col++;      }     col=0;      }      row++;       for( row = 0; row<data.length; row++){    for( col = 0; col<data.length; col++){               system.out.print(" "+data[86][1]);    }    system.out.println();      }         }  } 

it gives output 0.0 0.0 0.0 0.0 please me print file in array form

you print system.out.print(" "+data[86][1]); , initialize row 87 before reading.

you double [][] data = new double [87][2]; seems [row][col] set values using [col][row]. fix order consistent please. don't arrayindexoutofboundsexceptions on line:
data[col][row] = double.parsedouble(st.nexttoken()); ? (edit: saw other question, indeed aioobe ;) )

this while loop never run: while((line = bufrdr.readline()) != null && row < data.length). initialize row 87 equal data.length , statement row < data.length false.

edit: i'm stopping here now. i'd suggest throw program @ debugger , see code does.
