Bewertung und Feedback des Lernenden für Java Programming: Arrays, Lists, and Structured Data von Duke University

I found some of the questions quite challenging as opposed to the programming concepts. The questions specifically in the 4th week Quiz need to be reworded as they are a confusing bunch. But thanks for making a great content and giving me the right amount of information and domain knowledge to understand some important Java concepts.

The course is really nice and have some fun to do assignments as well. It helps in learning different data structure and the best part is using them in those assignments to answer the quiz. At times some of those lectures felt like they went to fast when describing what to do when you write the code. But overall a nice course.

The content of the course was great! The instructional videos taught a lot of concepts in detail, but some more, optional, assignments could have enhanced the course by providing extra practice for the concepts. Overall, I felt like I learned a lot in this course and would like to take the next one!

One of the toughest in the specialization! However I really enjoyed doing it!.it was challenging finding out the answers of the quizzes. One disappointing fact is that there are still few bugs in some of the answers. One piece of advice.. Always go through the discussion forums when you are stuck.

Useful course. Helped me gain a solid understanding of OO programming in Java, though I feel that the part where HashSet came up was too rushed (might want to reassure students that they will learn about why HashSet is faster when they learn about data structure in the future)

The mini-project was good. I didn't like that so much of the code was provided, as I wanted to have to figure it out myself. However, I see why this is necessary as the weeks go by, since issues with code will propagate into the following weeks if it wasn't provided.

I found this course particularly tough. I had to take it slow because of work and family and rather than 4 weeks it took me 4 months. But in the end I felt I got the intended knowledge.

Some sections are hard without knowledgeable mentors in the discussion forums.

Thank you for the course. The professors explain things with great enthusiasm and artistry. The main topic of the course - breaking ciphers is very interesting for me. Because of this interest I was completely involved into the course.

Thank you again!

The amount of learning in this module is huge! If you have never worked with HashMaps and don't know what this is, you may spend quite a bit of time trying to understand. That time will probably be spent reading material external to the course.

Its a great course! Assignments are really good and takes time. A bit lengthy and few things stretched out, apart from that a good course if you wanna practice and have time. learning content is less. Not for Beginners!

Need sample code for mini project as sometimes it is difficult to understand what to do in assignments... Some functions code get complicated as to what our instructor wants us to do vs what we think is possible

this course It contains many new information about it, the difficult and difficult Java also, the duties need a lot of thinking and research, but all of this helps in a deeper understanding of the Java language

The course is ok, but some lectures seems to be too slow paced, while the programming assignments tend to be difficult for a beginner programmer, since some issues are not covered in the lectures.

Learned a lot from the course, but the amount of programming assignment and number of Qs to complete the module (especially week2) was absurdly large. Could be split into separate sessions.

Very difficult material in week 2. Took a lot of effort to get through, but was worth it. I am continuing to learn about Java and writing more fluid programs in this specialization.

The cracking of Vigenere cipher requires some serious DFS and pruning.

I don't think that's quite achievable for a Java newbie.

Still, I had a great time with Python in this course.

Great course with clear level of difficulties laid out for each sub courses. But the course content jumped between cryptography and other materials making things hard to remember.

It was my one of the best Java courses ever done.The course would have been much better if there was some more talk about different manipulation on the structures being taught.

The assignments were not clear and I didn't know if i should go back and use my Caesar code to get some of the answers for the assignment. it would be nice to hint a bit more

Maybe this course for me are the most difficult, but the teachers, the teaching method and the spirit of Coursera in the mate´s class are the best.

6th question in final quiz is really hard for non native english speakers. Please avoid questions with multiple selection and with lots of text.

I really enjoyed and got some skills from this course but I think this course would need to take some more time and give deep knowledge.

The course challenges your brain to use the Data Structures in different possible ways.

It's a good course to implement Data Structures.

Some concepts used in Week 2 were introduced/ explained in more detail in Week 3 so I struggled in Week 2 but Week 3 was a breeze.

Week 3 and week 2 were almost same apart weblog stuff,

so I guess so more core topics can be added to week 3 to make it tougher.
