Object-Oriented Hierarchies in Java is the third of a series of courses in the Core Java Specialization. The Core Java Specialization is part of a series of programming specializations, derived from LearnQuest's private Java Bootcamps, designed to provide the skill set necessary to be hired as an IT developer using Java in many corporate environments.
This course includes hands-on practice and will help you build on your knowledge of the Java language. After completing this course, you will have a deeper understanding of how to effectively implement and use inheritance and polymorphism in Java. To be successful in this course, you should have taken: - Course 1: Introduction to Java - Course 2: Introduction to Object-Oriented Programming with Java or have equivalent knowledge.
In this video, we will introduce you to this course and explain what you will learn.
This module foreshadows the entire course, covering O-O Relationships, Inheritance, Polymorphism, Interfaces, Aggregation, and Design Guidelines. The following modules revisit selected topics in more detail.

Interfaces are the key to polymorphism in Java, since Java requires inheritance in order to implement polymorphism, and classes are limited to the single inheritance graph. This module goes into more detail on interfaces and polymorphism, and includes discussion of new Java 8 features, such as default and static methods, Functional Interfaces, Java Lambdas, and Method References.

Just as the first module served to foreshadow the entire content of this course, this module serves as a brief capstone, with a conceptual discussion of polymorphism mechanisms in Java, and practices for ensuring that polymorphism is an option in your programs.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.
