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.

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.

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.

Great Course, really loved it.

well prepared, thank you so much!

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.

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.

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.

Super great course! I would recommend this to any developer.

Superb course! Covered most of the topics in a very fluid manner. Could not stop once started the course.

Great course

this course packs quite a punch!

Very good Course!

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.

Loved it

Many thanks to all the people who created this course! I really learned a lot about data structure (LinkedList, tree, etc) and I am feeling much more confidence in programming after taking this course.

Although some of the assignments were difficult for me (I stucked a lot), but I am really happy and proud when I got full score from the grader :) Really recommend if you have programming experience but new to data structure!!

Very clear and intuitive explanation of data structures. Well-prepared and fun assignments.

Great course!

Excellent course! I truly recommend this course. Christine Alvarado, Mia Minnes and Leo Porter have created a great course on performance and data structures. You get to learn about regular expressions, Big-O notation and searching data structures such as trees and tries. I especially enjoyed the programming assignments that Christine, Mia and Leo had prepared for us, fascinating real life examples.

It's really well made, everyone who took this course should be very proud of the program they made during those weeks.

Excellent for those eager to learn about more advanced data structures in Java, specially tries.

Thank you!

Please keep up the good work.

Cource is too good
