Java offers three basic types of loops: FOR, WHILE, and DO&WHILE. Their fundamental function is executing a block of code repeatedly, based on a Boolean condition (Farrell, 2014).

Introduction With JavaScript-based AJAX, MVC, and Functional Programming, application design has been made simple for developers. JavaScript-based AJAX comprises JavaScript and XML technologies used by application developers (Singhal and Jain, 2017, p.13). MVC plays an integral role in developing an application because it helps build a user interface (Ratnayake, 2017, p.9). It separates an application…

Inheritance is one of the core concepts of object-oriented programming. It allows classes to receive, or inherit, all the behaviors and attributes of other classes (Farrell, 2016). Classes that inherit from others can still have behaviors and attributes unique to them (Farrell, 2016). Therefore, inheritance is a useful technique when creating objects that are sufficiently…
