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

Takes you by the hand to continue understanding Java. I used to HATE Java. Now it has become like Whisky, an acquired taste.

I'm happy that coursera has such a great courses like this one. So far I know that I'm on a good way to become a programist.

Its good way to master in programming because in this course explain more and practically so its more useful to understand.

I thought the examples and problems worked in the course really helped me towards getting a better understanding of Java.

Great course. Was not easy for me.

Requires lots of work. Everything is structured very logically here and it helps a lot.

Awesome course. Got deep understanding Java HashMap and HashSet classes. But the contents over ciphers should be updated.

Another great course! It gets gradually difficult but not too difficult and the projects are great! I totally recommend!

I really struggled for every assignments but it also helped me a lot getting used to the concepts I got from the videos

Great java practice. If you dedicate yourself to complete all the exercises, you will become a java programming machine

It was a great course to enhance your knowledge in Java, Specially Log reading, And the best part is it isn't lengthy.

Great interesting practical course as the previous one! There were a lot of coding practice, thank the Duke's team!

Excellent! I am very satisfied, because you taught with very interesting problems. i am learning a lot. Thank you!

Great Course. The materials are rich and practical. And moreover, the assignments are challenging and interesting.

The course is nice and teaches a lot of good concepts in Java. The last week with the mini project is really fun.

The course is very interesting, as well as the mini-project. I had a great pleasure with it. Thank you very much!

Well structured programming assignments provide lots of practice applying the concepts taught. Excellent course!

I loved this course. It was challenging but not too difficult that I couldn't do it with a little bit of effort.

it was awesome learning about array lists, structured data. looking forward to learn new such innovative things.

It's hard initially but progressively easier as i become more familiar with the concepts from all the practices.

Great intro to Arrays/LIst/HashMaps and other container classes in Java. Lots of hands-on java coding exercises.

Brilliant course, well structured lecture and assignments help to learn concepts more effectively.

Worth doing !

Well Paced course that was just challenging enough to be straight-forward while still teaching me new things.

The course offers a good introduction to object oriented programming methodology and to map data structures.

Amazing course, well sturctured and entertaining with interesting problem sets. Learned a lot of new stuff!
