[ben riches]

Hello everyone i have this code which is below but i am stuck with how i can printout how many tokens are in the first line
could anyone give me some ideas please
thanks

 
 import java.io.*;
import java.util.*;
import java.lang.*;
import java.util.StringTokenizer.*;
import java.sql.*; 
public class RT3 {

public static void main(String[] args) {

String token = null;
String currentToken = "";
Hashtable hh = new Hashtable();

try {
Vector v2 = new Vector(100);
Vector v = new Vector(100);
FileReader file = new FileReader("Work.csv");
BufferedReader buff = new BufferedReader(file);
String line = buff.readLine();
StringTokenizer s = null;
boolean eof = false;


while  (!eof){
s = new StringTokenizer(line.trim(),",",true);
boolean lastToken = true;
  

while (s.hasMoreTokens()) {


 token = s.nextToken();
     if (lastToken){ 
 if (token.equals(",")) {
 v.add("");
     }
                       lastToken = false;
 } 
         if (! token.equals(",")) {
 v.add(token); 
     } 
else { if (currentToken.equals(",")) {
 v.add("");

 } 
} 
currentToken = token;


}
 if (token.equals(",")) {
  v.add(""); 
}      


line = buff.readLine();
if (line == null){
eof = true;}
}

buff.close();
}catch (FileNotFoundException fe) {
System.out.println("Error - - " + fe.toString());
}catch (NumberFormatException ne) {
System.out.println("Error - - " + ne.toString());
} catch (IOException e) {
System.out.println("Error - - " + e.toString());

    
         
}
}
}

Well it looks like you are processing the entire file, instead of just the first line.
You don't need the

  while( !eof)

loop if you are only concerned with the number of tokens on the first line.

I don't see where "v2" is used, I don't see where "hh" is used, ...
Get rid of code which you are not actually using. This will help you understand what you are trying to do.

I would suggest, as a start, that you read in the first line, tokenize it, than print out each token on a seperate line.
You need to understand what you have in "s", before you can start processing it.
