i want a number in a specific range in pattern matcher..for example a number should only be in the range of 6-9 digits...if it exceeds or decrease it should show an error.Here is the code which i am trying...i this it checks for 10 digits...but i want it in the range of 6-9
import java.util.regex.Matcher; import java.util.regex.Pattern;
public class ValidatePhoneNumber { public static void main(String[] argv) {
String sPhoneNumber = tf.getText(); Pattern pattern = Pattern.compile("\\d{10}"); Matcher matcher = pattern.matcher(sPhoneNumber); if (matcher.matches()) { System.out.println("Phone Number Valid"); } else { System.out.println("Phone Number not valid"); }
} }
import java.io.*;
import java.util.regex.*;
class pmatch
{
public static void main(String args[])throws IOException {
Pattern p=Pattern.compile("[0-9]{9}|[0-9]{8}|[0-9]{7}|[0-9]{6}");
System.out.println("Enter no.");
BufferedReader br=new BufferedReader (newInputStreamReader(System.in));
String exp=br.readLine(); Matcher m=p.matcher(exp); boolean b=m.matches(); if(b==true) System.out.println("Valid number"); else System.out.println("Invalid number"); } }
Here is a code that validates phone number.
import java.util.*; import java.util.regex.Matcher; import java.util.regex.Pattern; public class ValidatePhoneNumber { public static boolean validatePhone(String phone) { return phone.matches("^[0-9]{6,9}$"); } public static void main(String[] argv) { Scanner input = new Scanner(System.in); System.out.print("Enter Phone Number: "); String phone = input.nextLine(); while (validatePhone(phone) != true) { System.out.print("Invalid PhoneNumber!"); System.out.println(); System.out.print("Enter Phone Number: "); phone = input.nextLine(); } } }
