In an online course you cannot expect us to learn only by the practise without a little of theory. In the assigments you incorporated things we didn't know and you explained a few there but it is not enough. Here we don't have a regular following like in a real course so we have to learn everything by the theory and only put in practise that we learnt there.

The data set in the genome studies was too large for mine - and judging by the forums - others computers memory to compile. Which made some of the exercises/tests very difficult to complete. Also, a few of the tests seemed to have at best unclear questions and at worst plain wrong. &-:

I actually enrolled for this course with a intension to learn java programming from the basis.But i dont get the concept of class,interface,oop etc.this course help me to write the simple program.

I'm unable to understand the tutor language... I feel like they are going fast and I'm unable to catch them.

sorry and I don't want to continue this course anymore.

It would be better if Java was taught from the scratch with syntax and semantics, instead of using BlueJ and external packages at the first instant only.

Way too repetitive. It gets extremely boring doing basically the same tasks with Strings over and over and over and over again. And then some more.

Fantastic course. Great assignments and lectures. Low score because the workload is excessively high and overwhelming for novice programmers

This course is really hard, and I am having ALOT trouble understanding it. Overall, it is not one of the best courses I have taken.

Not a very good course for Java. The introduction in week 1 is taught roughly.

I do not think it is helpful enough.

It just tells lots of basic things.

hard to get help, its not very beginner friendly..

This Course does not cover the Java Basics at all

The lessons are not easy to catch for a beginner

Videos are not okay. Could be more explanatory.

nobody to help with IDE problems!

Very challenging

I really want to know if the people giving this course glowing reviews are real people that have taken other programming courses on Coursera. I've done a bunch, and this may be the worst one that I've seen. It's definitely not accessible to beginners. If you can't already program well in another language, this will be unintelligible to you.

The lectures are super easy to follow because they are written like they were designed for audiences of small children. As soon as you go and try to do the assignments, you'll notice that they are very difficult and that watching the videos (even multiple times) does nothing to prepare you for what you are doing. Even the first exercise is brutally hard if you don't already know what you are doing with respect to object oriented programmings patterns. They give you a big file with some prewritten functions and then expect you to be able to write several functions to solve increasingly more complex problems based on the methods from their custom class. There's a very good chance that you'll look at it and just stare blankly because nothing prepares you for what you are expected to do.

The big issue that I can't get over is that although I can sort of stumble my way through things, I don't feel like the course explains how and why things work the way that they do. Why am I doing [insert whatever task]? I have no idea really.

When you realize that you have no idea what is going on, you'll go into the forum and notice that every question you have has been asked by multiple people already, often going back several years. It's obvious that nobody maintains or looks at these discussion forums.

Everyone else has pointed it out, but it's worth saying again: BlueJ is terrible. Why one earth would you force people to use an IDE that nobody else uses? Being forced to use BlueJ alone is a reason to not finish this course. Just don't do it--it's awful.

I also think it's terrible to write custom classes for a course and then make the course completely dependent on them. Why do courses do this? It literally makes most of what we are doing useless outside of the class.

This corse was horrible. I tried very hard for a few months to grasp the concepts and learn at the pace that was required. However, even with a small amount of programming experience, these courses made little to no sense. Also, the duration of the courses was WAY off, I work a full time job, so I was excited about taking this class in my free time after work and for an hour or two on the weekends. However, I found that I had to set aside at least 3-4 hours EACH DAY to accomplish the tasks and try to squeeze information out of instructional videos that just wasn't there. The instructors overcomplicate topics, while speaking in a tone as if they are talking to children. Some of the information that was mentioned I could not find anywhere else online, so I was stuck trying to take notes from the readings and videos, only to get to the quiz and NOTHING lines up with what was taught. They attempt to teach you from the ground up, however, they jump around from topic to topic to where it's impossible to feel like you're actually building on what you have previously learned. Even when I felt like I understood SOME of the information, the quizzes made me feel like a complete failure as the questions and answers are vague.

I came here from Udemy thinking that the courses here were better produced and easier to understand. Man was I wrong. Not only do these videos look dated (when were these videos made? 10 years ago), but the IDE they make you use looks like it was made in the 90s. The instructors DO NOT explain anything in detail, leaving me feeling even more confused than when the video started. Most videos are 5 minutes long and the instructor rushes through the topic almost like they don't want to be doing it. As for the readings, NO ONE learns coding through reading. But even if they did, the lectures you force the students to read are almost in a different language. If I need a dictionary and other YouTube videos to explain what I'm reading, then you've failed in your goal of teaching. When you expect me to pay $50 a month for a course, I expect better quality and production than what I can find for free on YouTube. To anyone reading this.... SAVE YOUR MONEY and find free stuff on YouTube, or pay $12-15 on Udemy and get better lectures from there. To anyone who made these video...DO BETTER! This low quality crap is why people get demoralized when they want to learn code and give up.

The problem instructions have errors or they are incomplete. I saw that students from 2-4 years ago asked the same questions which they were asking most recently about 1-2 months ago. I think the course staff has missed an opportunity here to improve the documentation and learning experience. Moreover the problem statements for the assignments are vague and ambiguous and you are left scratching your head and browsing through forum posts to figure out where you went wrong. Sorry to say, overall a frustrating experience. The challenge is not in problem solving & coding where is should be, but in trying to untangle confusing and incomplete assignment descriptions.

Constant mistakes appear in the lecture especially reading materials. it can mislead the students.

for example:"As always, when you’re done writing your code in the getLargestSide method, remember to add the code to call the getLargestSide method in the testPerimeter method and add the code to have the system print the output (the same way we did in the last exercise). As always, this is a great time to compile and test your code, and if you run this code using example1.txt as your shape file, then the longest side should be 5.0."

I think answer is not 5. mentor please double check. PS I've found several mistakes in this class. It needs to be improved.

This is not a beginner's course and some questions are not easy as the staff rated, I think is a good course for intermediate people. To answer all the quizzes section you might investigate a lot. We got a life too! Many of us are not in school anymore we have a job and a family. My recommendation, please explain a little more the programming structures like CSVParses is a list or something? I never got it.

PD: The way you use tricky questions is not good to improve programming skills, please put hint at least i.e. " What is the number of boys' names in the file yob1905.csv?"

Regards.

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.

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!
