What you'll learn

By using methods and encapsulation to their full potential, you can write robust applications that will evolve nicely over time. In this course, Working with Methods and Encapsulation (Java SE 8 Programmer I Certification 1Z0-808), you'll learn to model real business domains using methods and encapsulation to prepare for the 1Z0-808 certification.

First, you'll explore how to declare methods with arguments and return values. Next, you'll discover how to use method overloading and overriding in Java to create polymorphic code. After that, you will understand how encapsulation keeps your classes safe to use by hiding away implementation details, and you will see some applicable techniques to enforce encapsulation. Finally, you'll learn how to use constructors and static members.

When you're finished with this course, you'll have the skills and knowledge of using encapsulation and methods in Java which are needed to create modern software applications, and take the Java 1Z0-808 exam.
