The Java Object-Oriented Approach (Java SE 11 Developer Certification 1Z0-819)

Dan Geabunea

Learn the fundamental concepts of OOP that you can use to write domain-oriented and flexible code. This course covers the “Object Oriented Approach” topic from the Java SE 11 Developer Certification 1Z0-819 and can be used as an exam study guide.

Business needs are becoming more and more complex and software needs to keep up. In most cases OOP is the most pragmatic and elegant way of modelling today's software solutions. In this course, Java Object Oriented Approach (Java SE 11 Developer Certification 1z0-819), you’ll learn to model real business domains using OOP and prepare for the 1z0-819 certification.

First, you’ll explore some of the basic concepts of working with OOP like objects, classes, packages and constructors. Next, you’ll discover how to add state and behavior to your objects using instance and static fields, methods and classes. Finally, you’ll learn how to use encapsulation, inheritance and polymorphism to deliver more robust software applications.

When you’re finished with this course, you’ll have the skills and knowledge of using OOP effectively in Java which is needed to create complex software applications and to take the Java Iz0-819 exam.
