I loved the you teaches us.

I loved the the step by step way to write the code.

Loved everything.

Sanuj, with lots of love from India!!

Applying JAVA to the problems of (ancient) cryptography. Very entertaining application examples with lots of hands-on experience.

Very challenging. For absolute beginners maybe a little bit hard. Above all, you also get some programming experience in Java.

Excellent tutorials and very challenging problem sets! I would highly recommend this course for anyone looking to learn Java!

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

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.

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!

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

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 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!

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 !

This is much better than the previous one. The quiz and project design are much more reasonable.

Good work!

Nicely paced course for beginners to Java programming and the programming assignments are really exciting.

Very well instructed course. It was very helpful to throughly understand how ArrayList and HashMap works.

This course has just the right amount of support so that you try things on your own without getting lost.

Great. Makes you think a lot, while doing fun projects, not the usual programming made boring teaching.
