Chapter 2. Real-World Objects to UML Diagrams and Java 9 via JShell
In this chapter, we will learn how to recognize objects from real-life situations. We will understand that working with objects makes it simpler to write code that is easier to understand and reuse. We will learn how to recognize real-world elements and translate them into the different components of the object-oriented paradigm supported in Java 9. We will:
- Identify objects from applications requirements
- Capture objects from the real world
- Generate classes to create objects
- Recognize variables and constants to create fields
- Identify actions to create methods
- Organize classes with UML diagrams
- Use feedback from domain experts to improve our classes
- Work with Java objects in JShell
