Aadhar Format

Edit Validate rules

Format - 1 (With Space)

• Ex: 2341 1234 1234

// Regex to check valid Aadhaar number 
String regex= "^[2-9]{1}[0-9]{3}\\s[0-9]{4}\\s[0-9]{4}$";

// Compile the ReGex
  java.util.regex.Pattern p=java.util.regex.Pattern.compile(regex);

// If the string is empty, return false
if (theValue == null || theValue.trim().equals("")) return false;
theProperty.addMessage("Please enter valid Aadhar Number");

// Pattern class contains matches() method to match the given string and regular expression
java.util.regex.Matcher m = p.matcher(theValue);
return m.matches();

// If the string is empty, return false
if (theValue == null || theValue.trim().equals("")) return false;
