Outdated course and not what I was looking for. It contains all assignments on a Java Swing application which is outdated too.

This course code is outdated and cant be accessed from newer versions of Java Fx.

I am very happy that this course is part of the Object Oriented Java Specialization - the one which has 2 courses from Duke and 2 courses from UCSD. If you are reading this, it goes without saying that you are interested in learning more about Java and getting certification - this course will do that but begin to blend in a lot more topics that are specific to Computer Science - topics like algorithm efficiency for sorting and finding data.

This shift towards Computer Science theory, as opposed to practical Java programming, may surprise you. This can be challenging material - but in the context of the course, you can evaluate how you feel about it without committing too much - since it's the final course in the specialization.

Regardless of your receptiveness to theory, the content is highly relevant in practice, just be warned that you may not breeze through this course. It will definitely be worth it though, as knowledge of these topics are what's expected of people with a Computer Science background in the field today.

There is no one participating or collaborating here! There's no way to get help.

Outdated java is used! Applets are not even included in latest Java versions.

Very solid review of data structures. In fact, I learned a lot of new things along the way like how to benchmark test Java code and how to properly use JUnit and other unit testing frameworks.

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.

This course illustrates the most common data structures well. With proper amount of practice with tests and an interesting project that you can play with. I especially enjoy building a linked list by myself. I hope we can also build a hash table in week 6. The hash table course gives a nice explanation but less practice. and we didn't have a chance to deal with a hash map. I also hope the explanations can go deeper. Overall it's a nice course and worth the time.

For someone who has some experience of coding but did not venture much into data structures - this is a superb course as it covers an introduction to data structures, their performance, test driven development, benchmarking and more. The lectures and project materials were simply great for introducing the concepts as they were challenging but not too overwhelming for the typical intermediate level beginner like myself.

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.

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.

Top class course with top class instructors. Later after completing the course I come back to this material to refresh the material. Top class instruction.

well prepared, thank you so much!

Great Course, really loved it.

The idea of applying linkedlists, hashmaps, trees to solve a commonly occurring problem of Word suggestions is cool. It allows the students appreciate the practical context in which these algorithms are useful. The assignments can be made a bit harder to make the learning that much more worthwhile.

Love this course combining the data structure with some basic real word problem

Introductory course to data structures. The lectures are good, however the assignments are too much guided. Sometimes you can get it done without actually understanding what is going on.

Dont Take this course if you want to learn updated OOPs concepts

This course is a excellent introduction to data structures and algorithms for beginners. The lectures are extensive, complete and very helpful. The assignments are challenging and stimulating. The project is the construction of a text editor with check spelling, auto-correction, suggestion and more. It was the first time I felt involve in a large project, and you learn a little bit of software engineering too. This is the second course in the specialization and it overcomes the previous course in every aspect.

I'll give five stars. The only thing I didn't like was the concept challenges, and not because of the challenges but because of the discussion with the UC San Diego learners. They are not beginners, they are actor pretending they don't know how to solve the problems when it is evident -at least it was my impression- that they are advanced students. I found them annoying and not helpful at all.

Very visual, they use a lot of images to help you to understand abstract concepts. They make very good use of symbols. Also, when some code may seem confusing, don't worry, because they are gonna explain it LINE BY LINE with arrows and boxes to help you to understand what it is happening, where it is exactly happening and why it is happening. Also, if you are a fast learner and prefer a simpler approach, they prepared different paths to complete the course, so they tell you which videos are better to skip and which ones you would like to watch. And they ALWAYS give feedback when you finish a quiz or an assignment. This is not my first course of this series, I also take Object Oriented Programming, also by them, and has the same good points. I completely recommend this course, either you are a fast learner or not.

Great course. I am learning so many things. This course has improved my structured thinking to start with a real world problems in many ways. I have adopted test-driven-development cycle for all my work which has improved my code quality significantly. All those real word challenges videos are a nice inspiration. My favorite videos are the "How I Struggled" because I am able to relate myself facing the similar kind of situation and got boosted to continue. Liked course structure. It works for me.

Mia, Christine and Leo are just awesome . Thanks for all your efforts. Really grateful to you and University of California, San Diego. Thanks.

This course covers some of the industry standard applications and they can be implemented. This really challenges the programmer to sit down and work some of the very good algorithms. And it shows the real usage of the Java data structures.

Professors Christine, Mia and Leo's teachings were very professional and helpful.

A word about the projects. After a student finishes the projects, they can confidently say they did something good with the data structures in Java.

Thank you for the course instructors and everyone who worked behind this.

Highly recommended for the serious Java programmers.

I love this class. There are a couple of data structure classes in Coursera and i think this class fits me the most. I like that it teaches data structures and how to use them in the real world. So, you will be building actual programs with the data structures you learn . It skips alot of the math stuff and I love it because i am not trying to be a "real computer scientist" . I dont need to know how to write a math proof on how a algorithm works what not. Maybe in the future when i want to do research, but as of right now, I just want to build cool software and have fun.

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.

This is one of the best series of courses I came along in online MOOC platform, such a brilliant course, this whole specialization is brilliant, such a interesting projects, I'm disappointed that I live in country that isn't that much wealthy to help this Specialization and to be able to do Capstone Project , but I wish all the best hope to finish all in time, this is in my top 3 online MOOC Courses and I saw a lot of them.

I wish all the best to this team and people that made this possible.
