Application design patterns

Application design patterns, which will henceforth be referred to as design patterns for brevity, provide solutions to common problems related to software development using a historically proven method so that you do not have to reinvent the wheel, as the saying goes.

Here we will cover some of the most popular design patterns, which are known as the Gang of Four (GoF) design patterns. We will also explore some fundamental object-oriented programming and design principles, known as the SOLID principles, that also serve as a basis for some of the more modern design patterns.

The GoF design patterns are generally considered the foundation for all other design patterns in software development. When using these famous design patterns, it is not only easy to re-use the code and the logic as prescribed by the design pattern, but it is also easy for other developers to read your code; when another developer sees the code, they will be able to tell that you...
