About the Course

How do Java programs deal with vast quantities of data? Many of the data structures and algorithms that work with introductory toy examples break when applications process real, large data sets. Efficiency is critical, but how do we achieve it, and how do we even measure it? This is an intermediate Java course. We recommend this course to learners who have previous experience in software development or a background in computer science, and in particular, we recommend that you have taken the first course in this specialization (which also requires some previous experience with Java). In this course, you will use and analyze data structures that are used in industry-level applications, such as linked lists, trees, and hashtables. You will explain how these data structures make programs more efficient and flexible. You will apply asymptotic Big-O analysis to describe the performance of algorithms and evaluate which strategy to use for efficient data retrieval, addition of new data, deletion of elements, and/or memory usage. The program you will build throughout this course allows its user to manage, manipulate and reason about large sets of textual data. This is an intermediate Java course, and we will build on your prior knowledge. This course is designed around the same video series as in our first course in this specialization, including explanations of core content, learner videos, student and engineer testimonials, and support videos -- to better allow you to choose your own path through the course!...

Great into to Java, instructors have clearly put thought in to the format with the choose your own learning style videos, and additional coverage where it may be needed. These have been very helpful.

The course curriculum is well designed and teaches students the basic data structures needed to be a successful software engineer. The project is good, and the weekly assignments are challenging.

Introductory course to data structures. The lectures are good, however the assignments are too much guided. Sometimes you can get it done without actually understanding what is going on.

Still the first weeks only repetitions from the predecessor specialization. But better assignments than the first course and not only repetition.

good materials, learnt a lot but human interaction is a desert think this course is too old maybe

I started the specialization without any kind of programming experience. Although I find the content very relevant, I believe the assignments can be overwhelming sometimes for someone with as little programming background as myself. Recommendation is to, instead of having the students build everything at the end of the weeks, divide the homework in 3 or more pieces and as the lessons progress, program just a bit of code.
