About This Course


You will also need to establish a Google account. 

Instead of trying to complete each lesson in one sitting, you should try to small pieces daily and expect to spend a good two weeks on this introductory lesson.

Spacing out your time on this lesson will better prepare you for the in-depth lessons that follow.

The main focus of this course is to learn about standard types of data structures.

This course will consist of the following topics:

  1. New java topics & Introduction to Data Structures (This is the lesson you are in)
  2. Big Omega (Big-O) Analysis
  3. Java Collections Framework
  4. Lists, Linked-Lists, Iterators
  5. Stacks and Queues
  6. Trees, Binary Trees
  7. Hashing
  8. Regular Expressions
  9. Becoming a Better Programmer (Miscellaneous Programming Topics)

In the sections that follow, we will offer a brief review of each of these topics.

Keep in mind that at the end of each full lesson, a set of graded questions or programming exercises will follow. You are permitted to go back and review any of the sections, websites and videos of your choosing as you answer these questions.

However, if you just study the questions and look up the answers in the material, you will do well on the questions but not as well when you take the tests.

Instructions for Completing the Programming Assignments in this Course

For each of the programming assignments in this course, there will be a strong temptation to look on the internet for similar code and to copy that. Although you might be able to get your projects to work with that strategy, it is highly likely that you will not do well on the corresponding exams on each topic with that approach.

Real learning on these important Computer Science topics can only come with working the projects from scratch.

As you complete each programming assignment in this course, be sure to demo it to your instructor before marking it done here.
