Validating phone number using Java

ValidatePhoneNumber

import java.util.regex.Matcher;
import java.util.regex.Pattern;

/**

public class ValidatePhoneNumber {

    public static void main(String[] argv) {

        String phoneNumber = "1-(80..2)-321-0361";
        System.out.println(phoneNumber.length());
        String regex = "^\\+?[0-9. ()-]{10,25}$";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(phoneNumber);

        if (matcher.matches()) {
            System.out.println("Phone Number Valid");
        } else {
            System.out.println("Phone Number must be in the form XXX-XXXXXXX");
        }
    }
}

The regex code accepts a phone number between 10-25 chars length. The chars can be numbers, parentheses(), hypens, periods & may contain + sign in the beginning and can contain whitespaces in between.

The valid phone numbers with the above regex validations are

1. +33 (0)1 60 72 91 62 - Mary contact number
2. 1-(802)-321-0361 - General sentiment contact number
3. 080-41483223 - Indavest land line
4. 1-(802)-321..0361 - Random contact number

Does it work with -

1. 8128128122
2. 812 787 7898
3. 812 897-8978

yup! all the three numbers works with the above validation.

Hi please help me.

how I can prompt the use that the phone number he/she input is invalid?

I need to put the codes here
private void saveButton3ActionPerformed(java.awt.event.ActionEvent evt) {.....}

Hi.
Need help here.
I have 2 input text where user must enter their phone number. Then if the phone number is match, it will go to other page, if not the user must re-enter the phone number. The problem is, how to compare the value that entered by the user and verify whether it is match or not?

@ainie89
you can achieve this by using this simple logic.

if( ! textField2.getText().toString().matches(textField1))
{
// do this..
}

hope it helps.
