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.

One of my favorite online courses so far! Both the video lectures and the programming assignments are very helpful, and they supplement each other nicely. I learned a great deal from this course and will definitely proceed to the next course of the specialization.

Grate course, really interesting and useful especially Algorithms.

Assignments are organized very smart way it really motivates to go deeper.

Thanks University of California San Diego for creating this course on and make it available for online study!

This course provided a very good foundation on trees, hash maps, linked lists, and other advanced data types. The programming assignments helped improve my confidence with Java and taught me useful things I could start applying at work right away.

Very good series for learning Java and OO Principles. The big application approach is very interesting as we can see the whole picture even when we know little yet. The interviews with software engineers are very enlightening.

Really liked this course! It tested my patience and logic....I am glad that I am finally been able to complete this with "flying colors :)"....Will take some break before the advanced data structure though! until then ...

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!

This course is great !! I have already taken DS course at university but I found that this course is much better ! add to that the guided project will give you an understanding from why we are learning those topics :)

Really loved the course and how every aspect covered was related to a real word application.

It is an awesome start to learn the basics about data structures and algorithms in order to move to more advanced topics.

Great Course - very clear instructions throughout the course and accommodate all levels of learners.

Note: This course has been established for more than 5 years so some of the materials need to be updated.

This was a challenging course for me. But in the best way possible! The programming challenges are interesting and the application of asymptotics is made clear and relevant throughout.

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.

Very good and ordered exploration of using a variety of datastructures in the most efficient way possible. Good for anyone who wants to know more about Strings in Java specifically.

This is a great course. If you ever feared (like me) about implementations of linked-list, trees, tries, you should definitely join this! It would make these things much simpler!!!

Brilliant course. Learnt a lot about Data Structures like Trees, Tries, HashMaps etc. The best part was implementing the back-end for the text-editor project. Highly recommend it.
