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 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.
von Zhu L•
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.
von Difan G•
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.
von Aditya G•
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.
von Goodwill T K•
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.
von Darshan J•
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.
von RADHIKA M•
The course challenges your brain to use the Data Structures in different possible ways.
It's a good course to implement Data Structures.
von Joe S•
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.
von 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.
von Chongjun H•
Useful and helpful, a millstone in the specialization path, but not so preferable if you only enroll this single course.
von Dieter R•
The final quiz has 3 difficult questions for which I could not find a good answer. Luckily my guesses were good enough.
von Zakir S•
Good course but not much help is available to complete assignments and hints are not very helpful when taking quizzes
von Cyan C•
Hope the mentor can be more responsive on forum, as the quiz is getting tougher and need more help on it
von Shridhar S•
It would be helpful if explanations of the problems in the quiz were made available after passing them.
von Ashutosh D•
A nice course on cryptography. Learned many new data structures like HashMap, HashSet and ArrayList.
von Nuggu S V R•
Great course. Learning Java Data Structures and Cipher encryption was fun.
Good material and problems

The wording of questions in tests is sometimes misleading, this was not the case in other courses.
von Orlando C•
It is a good start for Java programming. Is very much practice oriented and the videos are clear.
von Masaru N•
One of the most **practical** Java programming courses that I've ever taken.
Thank you so much.
von JP B•
This is a very good course for the price, assuming you are at the beginner level (like me).
von Pratap B•
Its good training and i gained more on java programming as Array, Lists. Structured data
