 String, text, numbers, I/O I part

An idea for validating the phone number field on a form..,

Does anyone have an idea for validating the phone number field on a form. I am

looking for something that will basically check this input mask 

*111*111*1111*

Where the 1 s are number s and the * s are either   . spaces, or any

other character like (). Please advise.

Answer1:  You could use a regular expression package. For example, Jakarta ORO:

http://jakarta.apache.org/oro/

Answer2: i m thinking regular expressions. See:

Answer: 

import java.io.*;

public class FileIO {

    public static void main(String[] args) throws Exception {

       if(args.length!=1){

           System.out.println("Invalid parameters!!!");

           System.exit(0);

       }

       File fl = new File(args[0]);

       FileReader fileReader = new FileReader(fl);

       BufferedReader bufferedReader = new BufferedReader(fileReader);
