Opening a tab delimited file and replacing a space

Question

Hi,
I am trying to open a tab delimited file with 4 columns and corresponding values under it. If no value under the column, 0 should be replaced. I used the StringTokenizer and the split methods, but this doesnt seem to work. Any ideas?
E.g
Title1 Title2 Title3
4 7
5 2
SHould be like this:
Title1 Title2 Title3
4 0 7
0 5 2
Thanks..

The answer, however, is no. Java is a strongly typed
language; there is no predefined manner in which a
String object can be casted to an Integer object
because a String is not an Integer.
However, if you'd like to create an Integer based on
the contents of a String, you can pass the String to
the Integer.parseInt(String) method. That method
will do one of two things: return the Integer object
representing the integer contained within the String
(if the String represents an Integer) or throw a
NumberFormatException (if the String is not an
Integer).Hi,
Thanks tvynr for your reply. Ok first things, sorry, I had written that post in a hurry. Yes i dont usually put capital letters for my fields. Also i did mean using the add method. Not the get..
And yes I have tried various different type castings. Just to see if one of them would work. And yes i did try Integer.parseInt() by passing in the string to get back its contents as an integer. *And yes the String content is an integer.
Heres a snippet of my code -
              List ArrScore1 = new ArrayList(); //List to store Score in one Array
              List ArrScore2 = new ArrayList(); //List to store same Scores in another Array. FOr comparisions
              List SCORES = new ArrayList();
              int dist1,dist2 = 0;
              float distance,percent;
                while ((record = br.readLine())!= null)     //To read from a file line by line from first line
                  recCount++;
                  String rec = record;
                  String [] ScoreScop = rec.split("\t");
                  ArrScore1.add(ScoreScop[4])); 
                  ArrScore2.add(ScoreScop[4]);
                } //End of While loop
             System.out.println("Total Records: " + recCount);
             for (int i=0; i<ArrScore1.size(); i++)
                for (int j = i + 1; j < ArrScore2.size(); j++)
                   dist1  = Integer.parseInt(ArrScore2.get(j));  //Error I get here is is Cannot resolve symbol. What does this mean exactly?
dist2 = Integer.parseInt(ArrScore1.get(i)); //Same error
distance = dist1/dist2;
percent = distance * 100;
SCORES.add(percent); //Again same error
} //End of j loop
} // End of i loop
I have included all the necessary packages as well. Including :
import java.io.*;
import java.util.*;
import java.lang.*;
import java.util.List;
import java.util.ArrayList;Any idea what I am doing wrong here?
