課程概述

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.

I have been following courses from this and the previous course about Java OOP were fantastic. This is also great but the assignment were too easy, not so much of that challenge compare to previous one.

Again the explanation and representation was good.

3.5-4 stars for some Data Structures and their performance. Few basic ideas and introduction about the gui of the project would make it 5stars.

I really liked this. Learnt a lot in java. Would have been a 5 start had it included some more optional assignments that appear in competitive programming contests like ACM-ICPC.

I would prefer if they give us directions to write most of the code and not give us almost all of the code. I feel that there is too much hand holding in these courses.

The course is really good, I've learned a lot. The only thing I am not happy about, is lack of posibility to check the assignments without having bought the course.

The course is great! I learned about different data structures and applied them in the context of a text editor program which is a fantastic choice of application.

Nice . But It could have been better if we ourselves were supposed to make the Trees and Tries instead of relying on the java's built in classes. I learned a lot!

This was a nice course but I spent a lot of time trying to finish it. But at in the end, I achieved my objectives and learned a lot of it.

Covers basics well. The video lectures are easy and simple to understand. Liked the assignments and they covered the learned content well.

Could be more challenging. But I really enjoyed the course!!! Highly recommended for anyone who wants to learn java and data structures.

The course is intro-level and well-organized. Perfect for new Julia users. However, it will be better if updated to Julia v 1.0+.

Good but it was also good to let the students do some of the codings, I found the coding part actually very simple and short

I can tell the tutors spent time on preparing the course. This is the most well-organized coursera course I took.

The course is extremely good. It would be still better if there is inclusion of basics to create a UI.

Not as goog as the first course because knowledge introduced in there is not systematic as I thought

The overall course is good. But might touch too little on Big O? Not sure. But still good course!
