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

Great task for beginner.

The course was pretty challenging (and occasionally frustrating) for a novice programmer, but doable.

I enjoyed the course, and came away with a greater understanding of computers and programming.

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

Best course ever

The subject and assignment choices in the course are very practical and enjoyable - the emphasis on cryptography provides a lot of interesting discovery and by the end of the course you're easily cracking very complex encrypted messages. I thought that the log parsing exercises had a lot of real world usefulness for me personally as well.

The course will train you to quickly conceptualize how to solve problems by writing methods that fit assignment requirements and get you on your way to being able to talk about problem solving the way they do at job interviews. I highly recommend this java course - it felt like it had a lot of value all the way through.

very helpful course

I like the way the instructors to deliver their classes.

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

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

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

Very insightful and challenging

amazing

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

Thanks! I learned a lot!

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.

Great course! It gets progressively more difficult as it goes by. Glad I took it!

Great continuation of learning the Java language!

An excellent course to learn nuanses of different data structures in java.

Codebreaking made the homework quite engaging, and the lectures and coursework made sense. Week3 is a little heavier than the other weeks, so bear than in mind!

Excellent course. Fantastic assignments and projects. The instructors do a great job of motivating the use of data structures. They also introduce object oriented programming in the process. There are a LOT of subtle programming concepts you will learn, for example, composing large complicated programs using small functions/modules, documenting a workflow, identifying when to use which data structure, etc. I highly recommend this course and this specialization. (I watched EVERY video, and completed EVERY assignment, mini-project and quiz in this course.)

process gradually towards success! course materials is perfect.

Good stuff.

I so much enjoyed this java tutorial class. The design of each clip/module is very humane and best for the learning from scratch. I have finished this class and the one after it (array list one). I feel very confident about learning Java language and I am heading for the next one (software design principal). I plan to finish all of the 5 courses and then buy the certificate so I will be sure I am not waste my tuition. I am leaving the 1st class (CSS, html) for the last one before capstone because it seems not so relevant to SDE training but more frontend/UI.

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