i make your code and it work right but it take first line in the file only and i donot know why

Code:

---

import java.io.* ;
import java.util.* ;

public class Sample
{
  public static void main (String[] args) {
    try {
      BufferedReader read=new BufferedReader(new FileReader("C:\txt.txt"));
      String s="";
      StringTokenizer st ;
      while(read.ready()){
        s+=read.readLine();
      }
      read.close();
      st= new StringTokenizer(s, ",\n") ;
      int[] ints = new int[st.countTokens()] ;
      int i = 0 ;
      while (st.hasMoreTokens()) {
        ints[i] = Integer.parseInt(st.nextToken()) ;
        i++ ;
      }
    }
    catch (IOException ex) {
    }
  }
}
