Good intro to ArrayLists, HashMaps and HashSets, but assignments are very repetitive.

Despite having some tedious assignments, this course impressed me. It taught me the new topics very well. I liked working on the last few assignments. I would recommend it to learners looking for a good course to learn Java and it's applications.

Actually, before I start this course I had not a good idea about OOP concept such as constructors, HashMap.now I have fair confidence about that. thank you duke university making such an arrangement.

The course was pretty challenging (and occasionally frustrating) for a novice programmer, but doable.

I enjoyed the course, and came away with a greater understanding of computers and programming.

Great task for beginner.

The subject and assignment choices in the course are very practical and enjoyable - the emphasis on cryptography provides a lot of interesting discovery and by the end of the course you're easily cracking very complex encrypted messages. I thought that the log parsing exercises had a lot of real world usefulness for me personally as well.

The course will train you to quickly conceptualize how to solve problems by writing methods that fit assignment requirements and get you on your way to being able to talk about problem solving the way they do at job interviews. I highly recommend this java course - it felt like it had a lot of value all the way through.

I so much enjoyed this java tutorial class. The design of each clip/module is very humane and best for the learning from scratch. I have finished this class and the one after it (array list one). I feel very confident about learning Java language and I am heading for the next one (software design principal). I plan to finish all of the 5 courses and then buy the certificate so I will be sure I am not waste my tuition. I am leaving the 1st class (CSS, html) for the last one before capstone because it seems not so relevant to SDE training but more frontend/UI.

Excellent course. Fantastic assignments and projects. The instructors do a great job of motivating the use of data structures. They also introduce object oriented programming in the process. There are a LOT of subtle programming concepts you will learn, for example, composing large complicated programs using small functions/modules, documenting a workflow, identifying when to use which data structure, etc. I highly recommend this course and this specialization. (I watched EVERY video, and completed EVERY assignment, mini-project and quiz in this course.)

I really appreciated for the effort to make this course possible, I have learnt a lot and I like to think I am becoming better java programmer. I think I might need to do a lot more exercise to get better. I found quite difficult especially Gladlib and Vigenere Breaker. I work as an automation engineer and I write a code every day but this was good challenging tasks and I enjoyed working on it. I have had a lot of sleepless night where I was thinking how to solve the specific issue. Thank you so much.

I took the full Specialization, so I'm going write the same review for each of the 5 modules.

This is a great course, but it's not for beginners. They ask you to do a lot of coding, which is great since that's the only way to really gain proficiency. And the code they ask you to write is, in my opinion, pretty hard for someone new to coding. My hat's off to someone new to programming who makes it through the five modules.

So, thanks to Duke for putting together a great course. It was very good.

Very useful course! But it is not challenging enough. My advice: more challenging assignments to be given, and do not give too many detailed steps or instructions in the assignments. Let students themselves to solve the algorithms. Overall, this course is very useful and I like the lectures of Robert the most! His logic is extremely well explained.

The course itself is well put together and contains the perfect amount of challenge for students who have completed the previous Duke Java courses. I have come to enjoy the odd quirkiness of the instructors and their videos, as they seem to embrace the fact that they must remain a bit silly in order to effectively engage students in this format.

Pros: The tutors are well prepared for the course! I can see their enthusiasm!

The content is very online-learning oriented.

Cons: As a person who is already familiar with programming, the material develops a little too slowly for me.

Overall, I think this is a great start for Java beginners, especially for those new to programming.

They love teaching, and you will get the benefit from it. You will get confidence in developing with Java by using data structures common to the language and solving really interesting problems!! It gets complex but they teach to the level they expect from you, so if you give your best you will feel rewarded :) !

The projects for this course were challenging and interesting, and the videos and activities provided excellent information and were well-presented and explained. I thoroughly enjoyed this class and learned a lot about how to program in Java by making use of hashsets, hashmaps, arraylists, and other structures.

This course was very hard but the idea of teaching Java Programming with the application of cryptography was a magnificent one. Cryptography kept me motivated to complete the course as it is an interesting study. Hats off to the teachers for organizing an interesting course and for teaching it really well.

The course was appropriately challenging and a sound use of my time. My goals for it were unusual, and it has satisfied them. I feel very strongly that most students should take it in sequence with the other courses in this group and will benefit greatly from it and from completing the entire sequence.

This is the second course I take about Java, following the specialization of Oriented Programming. This second course is even better than the first one as it becomes more difficult and practical. The course is still wonderful and the teachers are always good at motivating me. Happy Programming!

It was a superb course with rich course materials. I would like to thank moderators for proving such a great course contents and the easiest way to learn them. This course is very good for learning Software fundamentals to solve large problems that are required in Software Development.

In this modern world this type of courses are very important. If a student takes it seriously and do every activity by themselves then they will definitely learn skills one after another . I think if I will be persistent then definitely this courser will add much more value.

its challenging to the point that i got very interested and trying to complete the whole specialization. Duke amazing job and for someone who wants to get started is a very very good basis. It is a self study with some videos but the documentation will help tremendously.

Great course and excellent introduction to arrays, lists. and some other related data structures. This course, and the others in this Specialization are well explained with programming assignments that are at the right difficulty for someone starting of in Java.

Great and effective course. A little harder than the previous course. A good way to introduce to different new java concepts. I also get some knowledge of Cryptography. Every beginner and intermediate level java programmer find this course interesting I think.

This course is fantastically created for excelling your concepts in Java. The faculties are worthy of praise.Thank you Rodgers, Owen, Hilton and Robert for creating one of the best courses in coursera and teaching us amazing stuffs in java programming.

Like the first and the second courses of this specialization this course is really helpful for beginners in Java development. It is an excellent introduction to arrays, lists and data structures. The assignments are practical, interesting and realizable.
