PaytmLite - A command-line version of Paytm built with Java. • PaytmLite has utilities that are somewhat similar to that of Paytm. Paytm offers services such as online use-cases like mobile recharges, utility bill payments, and events bookings as well as in-store payments at grocery stores, fruits and vegetable shops, restaurants, parking, tolls, pharmacies, and educational institutions. • The project is based mainly on the concept of inheritance in java. Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object. It is an important part of an Object-Oriented programming system.
