1Z0-816 – Java SE 11 Programmer II: Object-oriented Programming in Java

In this 11-video course, you will discover object-oriented programming (OOP) basics, including how to create methods, overloaded methods, constructors with arguments, subclasses, and superclasses in Java. In the first tutorial, learners will observe how to create methods and constructors with arguments and return values, and then move on to creating and invoking overloaded methods in Java. Next, you will discover how to apply static keywords to methods and filter variables. In another tutorial, you will learn about the different approaches to applying access modifiers in Java, and then move onto exploring the application of the encapsulation principles to a class in Java. You will examine how to create and use a subclass and a superclass, and create and extend an abstract class. Following on from this, you will examine how to enable or implement polymorphism by overriding methods, and then learn how to utilize polymorphism to cast call methods and also differentiate object types from reference types. This is one course is a series to prepare for the 1Z0-816: Java SE 11 Programmer II certification exam.
