My confidence level in Java programming has grown significantly since completing this specialisation. It gave me the necessary knowledge and practice I need to take up a role as a software engineer.

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.

Pacing of this course was all over.
Interface and Abstract classes were introduced and the material and lessons were easy to follow. Sorting using bubble sort, caparable, and comparator operators were also easy to follow. The final week presented topics on exception and try/catch/finally, but provided no practical programs for a student to write to ensure the topics were understood.
The problem was in week 3. N-Grams meant to teach some very important concepts about Markov and predictive text, but failed somewhat since the quizes were not clear and the grading a bit harsh. In the quizes, problems were presented and you either had the right output or you did not. There was no checks available that allowed a student to figure out why code produced the wrong output. In other modules (and courses in this series), input was provided and expected out based on the input was provided to verify code was working correctly. Not in section 3 - you wrote the code, took the quiz, and if you got the answer wrong were left scratching your head as to why, since there were really no means to check.
Don't mistake this feedback as saying the course was bad - it was actually quite good. If the course material for week 3 is updated to include clearer instructions and some better checks to ensure code is working correctly then I will change my review from a four star (it's more 3.5 than 4) to a five star.

Nice course which logically ends the series of four. Finally explains why different duke.edu libraries were used as well as BlueJ, which seemed to be strange choise at the beginning. I've finally understood why interfaces and abstract classes are important and how to use it. I decrease the mark to 4 only due to week 3 tests unclarity around hashmap - I've never worked it out how to get to the test results on hashmap size - it was working fine on small samples, but not matching the answers which were in the quiz for the big files which took a lot of time from me and didn't bring satisfaction.

Generally, I like this course. The tasks are very interesting and require to spend some time on them. But what I don't like is IDE that teachers use in this course. I also think that whole week 3 should be redesigned, especially requirements, they are not very readable. You should add some testing utility or some cases to test and verify student output with teachers.

There are some super cool concepts in here, but one of the modules in this course (module 3) was messy. Even the instructors have agreed that some lectures should be improved upon. That module was so messy that although I managed to finish, I felt like I need to relearn the concepts entirely somewhere else.

A really nice experience learning the exact use of the object oriented style of programming. Different concepts like abstraction and interface are well taught. A little bit improvement can be done in the assignment section otherwise its great and also week 4 could be a little more interesting.

Decent. Moved kinda slowly, but it's for beginners, so what did I expect? This is a nice progression of classes for someone with no previous programming experience; if you have previous experience, in another language, you may wish to start with an intermediate course.

Good examples -- good basic instruction in videos, but most of the value is in working the exercises which use some fairly interesting real world scenarios. And some of the direction is as vague as specs you might encounter as well.

Good course to start with, BlueJ experience for the first time was amazing for specific to this course. and the real life example of earth quake and the interfaces were thought in such a nice way that it engage to listen and apply.

The idea of using interfaces and abstract classes were not covered sufficiently in my opinion. That said, I was still satisfied with the content being covered. Instructions on some of the exercises could have been better explained

It is a good course, but I believe it needs to be updated and that some quiz need reviewing. Sometimes it's really hard to understand what an exercise is asking you to do and there isn't much support.
