Apex Design Patterns

Chapter 2. Creational Patterns

Apex programming revolves around objects and classes. During the course of application development, we create multiple classes. Also, we create objects of these classes to satisfy business requirements. Creating an object of a class within another class, creates dependency between those classes. This is also known as tight coupling.

As discussed in the previous chapter, tight coupling is considered inferior, as it can negatively impact the code's maintainability and scalability. Creational design patterns can help us avoid tight coupling by hiding the object creational logic.

Creational design patterns can be considered in the following scenarios:

• Instantiating classes in the Apex Scheduler class. If we directly instantiate ...
