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.\n\nI enjoyed the course, and came away with a greater understanding of computers and programming.

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.
By Dinesh K K•
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.

Useful and helpful, a millstone in the specialization path, but not so preferable if you only enroll this single course.
By Dieter R•
The final quiz has 3 difficult questions for which I could not find a good answer. Luckily my guesses were good enough.
By Zakir S•
Good course but not much help is available to complete assignments and hints are not very helpful when taking quizzes
By Cyan C•
Hope the mentor can be more responsive on forum, as the quiz is getting tougher and need more help on it
By Shridhar S•
It would be helpful if explanations of the problems in the quiz were made available after passing them.

The wording of questions in tests is sometimes misleading, this was not the case in other courses.

It is a good start for Java programming. Is very much practice oriented and the videos are clear.

One of the most **practical** Java programming courses that I've ever taken.
Thank you so much.

This is a very good course for the price, assuming you are at the beginner level (like me).
