In this section we introduce the UML class diagrams for modeling object-oriented software systems and various types of relations among the classes. Inheritance is an “is-a” relation, which inherits the attributes and behaviors from its parent class. These concepts are very important when dealing with object-oriented programming languages such as Java, Smalltalk, or C++. Encapsulation is the separation of how a class is used from how its data is represented Abstraction is the related idea of hiding the details of how a class is implemented from its users Examples of these concepts will be. The ER diagram is the pictorial representation of the objects and their relationships. k. Welcome to the second article in a series introducing UML and object modeling from a Java programmer's perspective. Consider the differences and similarities between the classes of the following objects: pets, dogs, tails, owners.

Encapsulation is the technique of making the fields in a class private and providing access to the fields via public methods. UML (Unified Modeling Language) is the industry standard used to describe the classes and objects of an object-oriented application. Class Diagram provides an overview of the target system by describing the objects and classes inside the system and the relationships between them. Other design patterns require new classes, whereas Factory Method only requires a new operation. Class diagrams are the only UML diagrams, which can be mapped directly with object-oriented languages.
