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.

The lectures, assignments, and projects all encourage you to learn about how to design and use optimal search algorithms for text-based applications. I especially value how the discussions present the material in way that is relatively easy to see how it relates to search routines in general. My only complaint is that the instructions do not inform you about the constraints that the online grader implicitly imposes on you. This unfortunately meant that I was not able to submit code with further optimizations that I came up with.

The content includes interesting and useful Java programming examples. The lecturers are generally on top of their subject matter and can speak confidently without visible notes. The tests are thorough and you won't get away with only half-knowledge. If you take all the lectures and study the slides, you will generally get to the necessary level of understanding.

Amazing video lectures that help in understanding the concepts quickly. In video quizzes help make sure your thought process is right.

But The assignments are way too simple if we follow all the steps provided. Assignments have to be more challenging. Surely 5 stars if they add more challenging assignments to this course.

This is a good course for beginners and from practice important concepts. The projects are pretty nice, and the instructions and tests are pretty clear. I don't like that you can choose the path of the videos, but it makes you save time. Only that sometimes it is difficult to choose.
