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!

Great course for intermediate programmers. Complete beginners would find this difficult but still there is so much you can learn from this course. For people coming from another languages like C# or C++, it will be easier. Overall, recommended. Thank you, Duke University for this course.

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.

Like the first and the second courses of this specialization, this course is really great. The journey to learn new data structures continues, and I only can say this : this is by far, the best specialization to introduce java programming for beginners

Very good course, challenging in terms of testing your ability to solve programming problems using data structures like arraylist, hashset and hashmap. Using problems from basic cryptography keeps you motivated to complete the course.

i have found no problems in this course and i actually liked it and the assignments were practical and easy to understand. Good Job!

PS. If i have payed for specialization, the "shortness" of this course would be disappointing.

Brilliant way of teaching HashMaps, HashSets etc. I've enjoyed this course the most out of the first 3 courses in the Duke Java Specialization. A big thank you to the course instructors for providing such quality material.

Really good course assignments and resources! I hope the lecture slides can be improved. The course is rigorous, challenging and intellectually stimulating. I hope Duke can offer more computer science courses like this.

Duke's Java programming class has been the best course I have taken for all other courses. I really enjoy the structure, the video, reading, programming assignments. I feel I am learning Java indeed for real use.

The professors had a way to just bring me down to earth in this course..Humbled me completely. the content was well organized .

the silver lining in this course was that there was less hand holding by professors .

The course is really well structured. The projects are interesting and the projects meaningful and challenging. The topics covered are very useful. Looking forward to the next 2 courses in the specialization.

It is great for Java beginner without prior programming background. But for those who have prior programming experience and seeking for a quick jump start to Java, there might be more repetition than expected.

Good and practical training approach to solve real worlds problems. Assignments and quizzes are quite challenging and interesting. Greatly motivates us towards programming and problem solving skills.

The programming exercises are really interesting! They make programming much more fun to study. The lecturers are all great and the lessons are engaging. Enjoyed it greatly! Thank you Duke.

the course content was great , thank to the teaching staff . i was so much excited about the modules... the projects were also very good , and make me feel that i became a real programmer

Wow. This was a surprisingly challenging class. In the best of ways though. Some of the questions in the quizzes need some rewriting to clarify, but still very fantastic overall.

The homework is really helpful to master data structure in Java, while some of it is redundant. Learning this course takes more time than I expected, but it gives me a solid basis.

This is a very nice course. The teachers speak clearly and explain very well. The subject used to teach Java (cryptography) is interesting. Many thanks!

Kind regards, Wim
