课程概述

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.

A lot of very useful information. A perfect course for people familiar with the basics of java, and certainly a good continuation of the first course in the specialisation.

This course by Alvarado, Minnes and Porter was clear, interesting and well presented. In fact, it's one of the better MOOC courses that I've taken.

The assignments were of medium difficulty: not too easy but certainly not so difficult that you will get frustrated and give up. In addition, they are interesting assignments. As mentioned, the lectures are concise, clear and interesting. In fact, I recently signed up for another course on algorithms and dropped it because it was SO BORING. Also, I am taking a course on machine learning that presents algorithms. In contrast, that course is not clear whatsoever; if I hadn't taken this one then I would be very confused. Finally, I like how they have the Concept Challenges where students discuss a problem. The thought processes of multiple people talking through the problem was helpful for me.

As a result, I highly recommend this course to anyone who wants to brush up on performance calculations (i.e., Big O), basic data structures, and a few basic algorithms.

The work load in this course is more intense than the preceding course in the specialization, especially on week 3. Other than that, I think this was an excellent course. I'm definitely glad I took it, it taught me a lot of the things that I was looking to learn as an intermediately experienced programmer.

Great course!

I have learned so much from testing design using JUnit on Eclipse to Algorithm big O evaluation.

This course is really a delight especially due to the very cool project we built during the course.

Thank you!

I really liked this course and the way it was taught. Although I am a CS major, I really learnt a lot of other stuff from this course apart from learning the core content of Data Structures.

I'm graduated in System Analysis, not Computer Sciences, and learned to program only by experience. After 20 years it's a good deal but still I missed the theoretical background and this always annoyed me. I knew and used to make good use of all the structures presented in this course but never could quite explain how or why, or talk in asymptotic notations. Now I can. I didn't stop here, I do take some topics to deep dive during the lectures. It's being a great experience and I only wish I could have more time to keep myself always enrolled in some course.

Fantastic topics. Good explanations by Mia (instructor).

Keep doing a great work, guy! I have restored my confidence in programming now!

Are you good at data structures ? If not, this will be the best course to start with. You learn the data structure and implement right away in your project assigment. Very practical.

A good overview of some fundamental data types. The programming assignments are fun and reasonably easy to implement if you have some CS background.

Great stuff! Don't give up on the first assignment, the rest are more easier...
