Literally one of the worst courses I've ever seen in twenty years of studying. No evaluation (correction check) for assignments, no reading material is provided by the instructors (except for the two million free websites they refer which makes this course pointless.). I believe this course is meant to make the most money with the least contribution. I regret I paid one month for this course.

PS. If you want to know what a helpful course should be, you may take a look at the course "Python Classes and Inheritance" by university of Michigan. This course: 1-Has step by step reading material, 2-Benefits from an online Python interface that could be used for assignments and quizzes.

I'm very disappointed about the Baby Names quizes answers, It kept me 2 days finding the errors you set as correct answers, I had to modify my code in order to respond an incorrect answer. I can deal with Lecture erros like the one you stated that .getCSVParser(false) returns no header (False). The .getCSVParser(false) returns a header so the answer to getRank() returns an extra number wrong number that never gives you the rank 1. You should have fixed this error on the quiz so you don't frustrate the students with wrong answers. If you change the answers I'll change my one stars review to 5 stars.

I Just can't understand why the instructors make simple concepts difficult to understand. Take the example of functions video, why you need nesting of function, calling function inside a function when you explaining function for the first time. for God sake this course required no programming knowledge. I learned programming (10 years ago) and yet i am feeling difficulty to understand your complex definition and explanation of a simple language concepts. i am doing this course for the sake of DUKE Certificate otherwise i give this course 1 Star.

The course is just terrible.

It leaves an impression of being unfinished. There's a lot of knowledge missed out from lectures while being expected from the student in the quizzes.

Lecturers themselves have a very vague understanding of how java works and how to code in real life. What they say in some lectures is very misleading and gives either false or just insufficient understanding of certain mechanisms.

The examples are overcomplicated. They demand a full concentration on domain knowledge rather than on programming itself.

This course is a huge disappointment. It is impossible to start the first assignment due to lack of information or examples of any kind. Many of the students have posted the same issue on the discussion forum and we are receiving no answers from mentors. This specific class is extremely frustrating and a huge waste of time. I am not the only one who thinks this!!!!! Someone should fix this class before they loose a lot of subscriptions because students are frustrated!!!!!

Bad organized, too many typos, errors, uncleared and illogic things in the Assignments. I am almost at the end, but now I really quitting this stuff. I liked the Programming C from the Duke, but this one is a total mess. There are no Instructors and Teaching Staff to talk to in the Forums, just some Mentors, but that is not a big help, this Course is total left alone from the Authors. Andy Hilton is a good guy, should read the discussions and correct the errors!

Does very little to actually help you learn JAVA. Explains nothing about why the language works as it does.. Also it insists on you using their libraries and programming environments. You spend perhaps 20% of your time actually practicing coding, and the rest is wasted in libraries you will never use again. Such a waste

If you are a real beginner like me (having zero or little programming knowledge) and your time is limited, I think this course (or the specialisation) is not suitable for you. The assignments and quizzes are very time consuming. One week I spent literally 30+ hours writing and debugging codes for just one quiz.

Assignments are too advanced compared to the videos given. 7 minutes was spend showing how to code. However the entire final quiz on week 1 expects you to code new things that which were never shown in videos without any help. This was not the case in the 1st class in this series.

Using custom libraries is very bad for students. We must study java core not some custom libraries.

BlueJ also a bad choise, even the notepad or the vim are better for understanding the compilation process. Also there is no peer reviewed assignments.

Poor, very poor course, worse course structure. Instructor hasn't put any thoughts in how they should strucutre this course.Cover no basics, assumes lots of thing and term this course as beginner for Java where actually there is no Java taught.

Poorly designed and explained. You do not really gain much knowledge from this course.

I would not recommend my friends and basically others to take this course. There are far better courses out there for much cheaper prices.

Really poor job teaching java programming. I'm a beginner at coding at the teachers teaching this course are terrible. I don't want to take this course.

The assignments could be a little more well suited to people from varying backgrounds.

The current assignments are a little difficult for beginners.

Teaches you Java in a "toy" environment (Blue Jay) would be helpful to learn Java in Eclipse or another IDE that you would normally work in.

Use very specific environment that cannot be used in practice in the the Real World.

For a much better course, use UC San Diego versions.

Not organised properly. And it is stated that this course is for beginners. But the concepts and their usage is not properly explained.

Paying for course just to learn how to loop and make if else statements... I don't think this is the best way to learn java!

STRONGLY DISAPPOINTED! VERY CONFUSING! DON'T PAY FOR THIS -- NOT WORTH IT! This class is very poorly designed.

This course is not suitable for beginners at all, everything basic is skipped. Highly not recommended

Use of Duke own specialised librarie ~ not the best way of learning progamming for the real world.

The course is too boring, I am not sure if it is because of the language or the lectures.

This is all teached in Bluej which is tough to understand

Had to buy a SECOND JAVA book to get through this

My expectations were different
