Very good Course. The assignments were fairly challenging and required 3-5 hours per assignment.

The instructors were really good. This was the first course on Coursera which I fully completed. I liked working with a large software project as part of the assignments.

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 coursera.org 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 :)

Excellent course, packed full of information - A MUST for anyone who is learning the Java programming language. Lots of effort has gone into this course and is very well structured clearly defining topics week by week.

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 way to learn the Optimization of data method and modules.Learn a lot about Data Structures.Thank you Mia,Porter,Alverado and Specially Course era for providing such Quality Education Platform.Love you all

Wonderful! So much great instruction, great learning, and fun assignments! :-) I am feeling more and more confident with my JAVA programming, which is exactly what I hoped for, and I am having lots of fun.

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.

I really enjoyed this course thanks to the great teachers and the awesome project, it really was cool working with you all and I'm very excited to see you again in the next course of this specialization.

This course was amazing! The integrated project is the best thing about this course as it would keep you dedicated all the time and gives you a glimpse of how people work on the backend in an industry.

After so many years, I actually understood the core concepts of data structures. Thanks all three instructors. The amount of effort they are putting to make the things easy for the students is awesome.

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.

This course helped understand the utility of data structures in software and how to benchmark algorithms in order to compare their performance so as to choose the most efficient algorithm

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.

Amazing course, I learnt so much about interesting data structures and gained a new understanding of how important it is to choose the right data structure for a specific purpose.

Very good course. This is a very right course for Java learners, will be touched on all basic stuff that are needed in Java. I will highly recommend this course for my colleagues.
