I use StringTokenizer class to sort emails. You can use any character to sort out Strings.
For example, my file contains isuru@xcs.com; madusanka@qwe.com; roxniro@qwa.com... so I user ";" character to sort emails. You can use "@" character to collect user names of email addresses.
File Reader Class
import java.io.*; import java.util.StringTokenizer; public class FileReader { File file = new File("/root/Documents/emails.txt"); StringBuffer contents = new StringBuffer(); BufferedReader reader = null; String text = null; StringTokenizer st1; public void accessFile() { try{ reader = new BufferedReader(new java.io.FileReader(file)); while((text = reader.readLine()) != null){ st1 = new StringTokenizer(text, ";"); System.out.println("There are "+ st1.countTokens()+" email addresses!"); while(st1.hasMoreTokens()){ System.out.println(st1.nextToken()); } } }catch(FileNotFoundException e){ e.printStackTrace(); }catch(IOException e){ e.printStackTrace(); } } }
Main Class
/** * * @author Isuru
*/ public class EmailCounter { public static void main(String args[]){ FileReader app = new FileReader(); app.accessFile(); } }
