Great course, but some assignements are a little confusing

Slightly difficult course

The course covers a small list of topics concerning programming principles.

The principle of programming against interfaces is not covered correctly in the course.

The tests are sometimes time consuming and it's hard to find mistakes, although the topics itself are rather simple.

at first, it started fine, not extensive explanations but just righ.

At the end of week 3, it was a dissaster, it seems like they just put everything together in a rush. This is a waste of money and definitely not recommended.

So bad, I really don't understand the concepts introduced in this course.

The practices are very unclear. I was stuck for hours!

This is my fourth course in the specialization. I enjoyed all the courses in the specialization including this course. This course introduces the basics of software design using Java. But compared to the previous courses in the specialization this course lacks behind in quality. Especially, the assignments in week 3 are poorly explained and the lectures also don't provide necessary guidelines regarding them. Felt a bit disappointed at this. But overall, this was a good course. I would have given it a 4 star but giving it a 5 star taking the whole specialization into account.

I took the full Specialization, so I'm going write the same review for each of the 5 modules.

This is a great course, but it's not for beginners. They ask you to do a lot of coding, which is great since that's the only way to really gain proficiency. And the code they ask you to write is, in my opinion, pretty hard for someone new to coding. My hat's off to someone new to programming who makes it through the five modules.

So, thanks to Duke for putting together a great course. It was very good.

It was a great course! It is not easy as the previous courses in the specialization but it is worth taking it. The concepts of Interfaces, Abstract Classes, Comparator, Comparable and many more are covered in this course. It is quite interesting as it deals with solving problems related to Earthquake Data and Markov's Predictive Text Generation. Thanks to the Instructors for providing such a valuable course on this platform. #Enjoyed the #Course!

I like this course very much. The design of the course is very decent, and the lecturers are skillful. With BlueJ as a starter tool and introduce more advanced too at this point is a great idea for novice learners to avoid unnecessary difficulties at beginning. I'm looking forward to enroll in the Capstone course in this specialization and other related courses.

A self contained course wherein you learn basic objected oriented design principles that is often missed out in the industry during software development.

This course gave me a new perspective at software design. Coming from a procedural programming, this course helped me approach problems in a much higher level, easing the creation of a solution to a problem.

This course is designed for the novice and it is clear that a lot of thought has been put into making sure that the core principles of programming using Java are as easy as possible to understand.

The teaching material is superb, and when I used the forum I received excellent support from a very knowledgeable member of the teaching team,

Course design was good and assignments were challenging . Now as a beginner , I am more confident about Java language. I feel that for Week 3 assignments , clarity of instructions was not there compared to previous two weeks. So I had to look through Discussion forums for the hints... but overall it was amazing experience!!

It is an excellent course for those who intend to know different design constructs in java. The course material, practice quizes and tests are designed to help the student apppreciate and be reasonably proficient in these aspects. My sincere gratitude to the professors and their team for this successful program.

All the courses of this specialization are needed for ones who enter the world of programming. The course ensures that you will understand what you have to know by implementing quizzes, questions and exhausting exercises that can be solved using only the material of the course.

This class probably isn't as good as the previous two--but those had such high quality, they're hard to compete with.

Overall, I continued to become a bit more comfortable with java and learned some things that might help me with my data science potential in the future!

Fantastic course. Thanks to the instructors and students who helped put this coursework together. I've learned a tremendous amount about OOP and software design. Will continue on with the capstone couse to complete the specialization. Thank you.

Really Helpful course. It helped me a lot to become familiar with the Java language and enlighten me with the fact that java can be used to solve a wide array of problems, which i considered impossible and tricky when i used java earlier.

Never thought I would start this course with no coding knowledge whatsoever and now I'm writing programs to solve complex problems and I'm hooked. Great course and I would highly recommend it to anyone interested in learning programming.

Enjoyed this course and the examples used to learn algorithms (earthquakes data and predictive text). I did find that week 3 had a lot of work packed into one week. Otherwise, interesting and fun course.

Well designed and well structured with the packages, resources, programming exercises and practice quiz. I appreciate the team's hard work in delivering good knowledge on the subject efficiently.

I´m really shocking with the course, because integrate all concept, start a new concepts, and I´m felling great for accomplished. Thank you team teacher´s for the opportunity, you are great.

This nicely packaged course is learner centered. It engages the learner by enforcing practice through interesting exercises and quizzes. Kudos and Thumbs up to the team of great instructors

This course was another of many well-taught courses of Duke University. The GPS library use to find locations of earthquakes particularly of very interesting. Thank you Duke University

amazing material - solid learning for Java

one struggle - discussion boards don't seem to be monitored by staff most of the time - expect to do most on your own without teacher input
