Class InputValidator

java.lang.Object
theLocalLoop.InputValidator
public class InputValidator extends Object
This class is responsible for validating user input throughout the application.
It provides methods to ensure that inputs are of the correct type and format, such as integers, doubles, non-empty strings, specific options, valid passwords, and valid types. By centralizing input validation in this class, we can maintain cleaner code and ensure consistent validation across different parts of the application.
