Operation on a txt file..

1st is to obtain data from this text file n simply show in the console n then to show the information separated by commas under the columns of name: roll number: class: phone number: course:

secondly it's to tell that how much characters, integers, blank spaces are in the .txt file...

FILE DATA:

andre neil, 211, IT, 04130001701, BSCS
David miller, 219, CS, 0234000201, BSCS
Johnson, 344, Maths, 0523400000478, BS(Maths)

Code JAVA:

---

import java.util.*;
import javax.swing.*;
import java.io.*;
public class TestStudent{
 
public static void main(String args[]){
 
 
	FileReader fr  = null;
 
	BufferedReader br = null;
      String[] tokens=null;
 
try{
 
 
	fr = new FileReader("student.txt");
	br = new BufferedReader(fr);
  	String line = br.readLine();
  	while (line !=null)
	        {
 
 
				 tokens= line.split(",");
  	          System.out.println(line);
  	           line = br.readLine();
 
	         }
 
	br.close();
	fr.close();
 
	}
          catch(IOException ioex){
	      System.out.println(ioex);
 
	}
 
 
 
System.out.println("student no.1");
Student s1 =new Student(tokens[0],tokens[1], tokens[2], tokens[3], tokens[4]);
s1.print();
 
 
}

it's giving me just the last student's data

student class is another file just to show the columns headings accordingly...

The problem is when you read the data into tokens[].

Code Java:

---

while (line !=null)
{
	tokens= line.split(",");
	System.out.println(line);
	line = br.readLine();
}

'Tokens' can only contain data of just one student.
So in the loop 'tokens' is overwritten with other data all the time.
