Table of Contents Overview Concurrency and Parallelism Parallel Programming Available Constructs Real-World Applications Conclusion Performance requirements are important to consider when developing a solution. It is unacceptable to have a web service that takes several seconds to reply to a simple request. Therefore, the developer should consider the available methods of improving the performance of…

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). However, they differ in how they evaluate their conditional expression (Farrell, 2014). A WHILE loop evaluates its conditional expression before executing, therefore, it is possible for this…

Classes and objects are one of the key attributes in object-oriented programming (OOP). The general relation between the two can be described as is-a: a class describes a template for objects, while an object is a specific instance of a class (Farrell, 2014). The primary concept of this relationship is reusability  code written for…

Usage scenario Linear programming (LP) is used to find the optimal solution for functions operating under known constraints. Therefore, it is best suited for operating within a decision environment with certainty. Such situations are common in business and economics, where the costs are known, or when distributing limited resources. One example where both of these…

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…

The below UML Diagram it describes how a simple ATM Machine works. The customer must pass authentication before withdrawing money. UML diagrams help visualize and illustrate the whole project before the programmer can start working on the project (Milovan evi et al., 2019). The codding part and the development process will stay on track following…
