Good intro to ArrayLists, HashMaps and HashSets, but assignments are very repetitive.

Very helpful for the basic Java data structure.

I recommend skipping this course if you have done SOME programming before. This is a LONG course just to cover concepts of Array and hashes which really should be a one or two hour lecture. It is nice that you learn some beginner cryptography though. That said, some of the assignments were unnecessarily frustrating at times and a bit too long. While I think it is a good course. It wasn't right for me. A bit too basic and assignment too long for a subject matter I had a very low level of interest in.

Amazing Content. Lot of hard work has been put into creating it by the intructors!

Very interesting course with with plenty of really good assignments. Not so complicated, but still very useful for everyone, who starts learning Java

Very nice course.

Useful course. Helped me gain a solid understanding of OO programming in Java, though I feel that the part where HashSet came up was too rushed (might want to reassure students that they will learn about why HashSet is faster when they learn about data structure in the future)

Superb!!

Great course! I learnt a lot from it.

As always, very thorough and helpful (learning by doing "countless" tasks is a great way to go, from my perspective). Thanks!

Very insightful and challenging

This course optimizes your basics skills concerning programming with java and take you to the nest level. This course increases the workload, practicing and debugging your code.

New concepts are introduced like, Arrays, HashMaps, and object-oriented-programming.

Once more, the professors bring the extra quality and professionalism to this subject.

Still needs some reconfiguration to the quizes. I am not satisfied with those. Needs to be fixed!

This is a very nice course. The teachers speak clearly and explain very well. The subject used to teach Java (cryptography) is interesting. Many thanks!

Kind regards, Wim

No so much assignments

I really don't understand why BlueJ is used, while there are lots of other free Java IDEs (Eclipse, IDEAJ, etc.)

Also i don't agree with some OOP things you say. I don't see any point in creating a separate class for each test case, one class for every single functional class is more than enough (e.g. we need to test a class called MyClass with 4 functions, thus we make no more than one test class with 4 or less (or more) test cases. Especially when you can use JUnit tests)

I love this course. I really learned a lot from this course. Thank you those awesome teachers.

Best course ever

Pretty good

I really appreciated for the effort to make this course possible, I have learnt a lot and I like to think I am becoming better java programmer. I think I might need to do a lot more exercise to get better. I found quite difficult especially Gladlib and Vigenere Breaker. I work as an automation engineer and I write a code every day but this was good challenging tasks and I enjoyed working on it. I have had a lot of sleepless night where I was thinking how to solve the specific issue. Thank you so much.

Thanks! I learned a lot!

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.

This course is build in step by step which is very easy for me to understood as a beginner.

Very intuitive course, Projects teach you how apply your knowledge and think through the program.

I like the way the instructors to deliver their classes.
