What you'll learn

  • Learners will learn about linear data structures. Topics start with the different varieties of linked lists and moves on to stacks and queues.

  • Trees are introduced as the first non-linear data structure. Topics include binary trees, tree traversal, searching a tree, and self-balancing trees.

Code and run your first Java program about data structures and algorithms in minutes without installing anything!

This course is designed for learners familiar with Java basics and object-oriented programming. It provides a solid foundation of not just Java, but core data structures and algorithms topics that can be transferred to other languages. The modules in this course cover linear data structures like lists (singly linked, doubly linked, circular), stacks, queues, and introduces the first non-linear data structure trees. To allow for a truly hands-on, self-paced learning experience, this course is video-free. Assignments contain short explanations with images and runnable code examples with suggested edits to explore code examples further, building a deeper understanding by doing. You'll benefit from instant feedback from a variety of assessment items along the way, gently progressing from quick understanding checks (multiple choice, fill in the blank, and un-scrambling code blocks) to small, approachable coding exercises that take minutes instead of hours.

Welcome to Week 1 of the Linear Data Structures and Trees course. You will learn about abstract data types (ADT), the list ADT, the many variations of the list (singly, doubly, circular linked lists), as well as iterators.

Frequently asked questions

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. 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.

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.
