NumberRangeRule allows to specify the range of numbers which are not allowed in a password. Consider the following example.
import org.passay.IllegalCharacterRule; import org.passay.NumberRangeRule; import org.passay.PasswordData; import org.passay.PasswordValidator; import org.passay.RuleResult; import org.passay.WhitespaceRule; public class PassayExample { public static void main(String[] args) { //Rule: Special characters like &, <, > are not allowed in a password IllegalCharacterRule illegalCharacterRule = new IllegalCharacterRule(new char[] {'&', '<', '>'}); //Rule: 1 to 5 numbers are not allowed NumberRangeRule numberRangeRule = new NumberRangeRule(1, 5); //Rule: White spaces are not allowed WhitespaceRule whitespaceRule = new WhitespaceRule(); PasswordValidator validator = new PasswordValidator(illegalCharacterRule,numberRangeRule,whitespaceRule); PasswordData password = new PasswordData("abc&4d ef6"); RuleResult result = validator.validate(password); if(result.isValid()){ System.out.println("Password validated."); } else { System.out.println("Invalid Password: " + validator.getMessages(result)); } } }
Invalid Password: [ Password contains the illegal character '&'., Password contains the number '4'., Password contains a whitespace character.]
