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.

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.

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.

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

This is my second Duke course, i'll take them all they are great. And i like the feel when i finish it. I'm still a student, i finish one course every two weeks.

Codebreaking made the homework quite engaging, and the lectures and coursework made sense. Week3 is a little heavier than the other weeks, so bear than in mind!

Very interesting course with with plenty of really good assignments. Not so complicated, but still very useful for everyone, who starts learning Java

Thanks for the great course. But it would be very usefull to specify some of time the student spend studying to pass the course in the certification.

Very good material, congratulation for all involved in this great masterpiece. Thanks very very much for the knowledge, i'm very proud of you all.

It's great,especially the mini-project and it is quite a complex problem, it is well planned so that we can reach the solution step by step.

This course was fantastic. A great overview of data structures in java and excellent assignments that allow you to utilize your knowledge

Great class. Really enjoyed it. The guided lessons were just challenging enough for someone who has very limited programming knowledge.

I loved the you teaches us.

I loved the the step by step way to write the code.

Loved everything.

Sanuj, with lots of love from India!!

Applying JAVA to the problems of (ancient) cryptography. Very entertaining application examples with lots of hands-on experience.

Very challenging. For absolute beginners maybe a little bit hard. Above all, you also get some programming experience in Java.
