Java EE 8 Design Patterns and Best Practices

Understanding the advantages of design patterns

Creating an object-oriented design is a tough task. This is because we have several important elements to think about with regard to the scenario that we'll work in and the problem we'll solve. This includes defining the appropriate objects that we need to create in order to reach the solution; defining the granularity of objects and looking at what interfaces we need to create. These tasks need to be addressed during the creation process in design. Objects can be created to represent a real-world object or to represent a process with its algorithms and responsibilities. Furthermore, we even need to consider the number of objects, their size, and the interface we need to access.
