how do u do a count

Hey,

I have a .txt file which contains general book order info such as:

customer name: XXX,
book title(s) ordered: XXX,
order date: XXX,

which the contents are read in when java program is run, how do I do a count on for example the number of books ordered?

Thanks.

StringTokenizer comes to mind.

Yeah CornedBee is right. You could use a string StringTokenizer.
The data stored in your text file can be delimited by characters other then spaces if you want by passing in a string to the StringTokenizer as the second arguement. The problem that i found using a StringTokenizer though is that everything is parsed and returned. For instance if your data is set up as such.

customer name: John
book title(s) ordered: 125
order date: 09/11/02

you will get the following.

customer name
John
book title(s) ordered
125
order date
09/11/02

The code that produces the previous output is the following.

Code:

---

  import java.io.*;
  import java.util.*;
 
class Grabber{
    public static void main(String[] args){

  try{
  File f = new File("C://Java/text.txt");
  BufferedReader buff = new BufferedReader(new FileReader(f));
 
  while(true){
      String x = buff.readLine();
        if(x == null) break;
          StringTokenizer st = new StringTokenizer(x,":");
            while(st.hasMoreTokens()){
              System.out.println(st.nextToken());
      }
    }
  }catch(IOException e){System.err.println(e);}
  }
 }
