About the Core Java Specialization

This 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.

To be successful in this specialization, we recommend you have an understanding of the fundamentals of software development in any language. LearnQuest offers a beginning programmer specialization that can help you prepare. In the four courses of this specialization, you’ll quickly master the Java programming language and the packages that constitute its rich set of core libraries. We’ll provide hands-on exercises so you can practice your new skills. In Course 1, we’ll introduce you to the basic fundamentals of the Java language. Course 2 provides a refresher on object-oriented programming, and how you can apply OO to Java. We’ll introduce Java classes, instances and packaging. By the time you get to course 3, you’ll be ready to go deeper into applying OOP concepts in Java, including inheritance and polymorphism. In course 4 you’ll learn how to use selected parts of the Java SE Class LIbrary, including Generics, Collections, Java Streams, I/O, Exceptions, Annotations and Enums. While we'll touch on other important Java topics, such as database connectivity, Java EE and Spring, those topics are covered in greater detail in other LearnQuest Java Specializations.

Frequently Asked Questions

When will I have access to the lectures and assignments?
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.
What will I get if I subscribe to this Specialization?
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.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
