About the Course

Build on the software engineering skills you learned in “Java Programming: Solving Problems with Software” by learning new data structures. Use these data structures to build more complex programs that use Java’s object-oriented features. At the end of the course you will write an encryption program and a program to break your encryption algorithm. After completing this course, you will be able to: 1. Read and write data from/to files; 2. Solve problems involving data files; 3. Perform quantitative analyses of data (e.g., finding maximums, minimums, averages); 4. Store and manipulate data in an array or ArrayList; 5. Combine multiple classes to solve larger problems; 6. Use iterables and collections (including maps) in Java....

Actually, before I start this course I had not a good idea about OOP concept such as constructors, I have fair confidence about that. thank you duke university making such an arrangement.

Good and practical training approach to solve real worlds problems. Assignments and quizzes are quite challenging and interesting. Greatly motivates us towards programming and problem solving skills.

Great and effective course. A little harder than the previous course. A good way to introduce to different new java concepts. I also get some knowledge of Cryptography. Every beginner and intermediate level java programmer find this course interesting I think.

Like the first and the second courses of this specialization this course is really helpful for beginners in Java development. It is an excellent introduction to arrays, lists and data structures. The assignments are practical, interesting and realizable.

Like the first and the second courses of this specialization, this course is really great. The journey to learn new data structures continues, and I only can say this : this is by far, the best specialization to introduce java programming for beginners

So far so good. Very high quality, important resources. I have one suggestion, please share screenshots of codes written by instructors during the video lessons, so learners can write that code and experience right away. Thanks in advance!

Very good course, challenging in terms of testing your ability to solve programming problems using data structures like arraylist, hashset and hashmap. Using problems from basic cryptography keeps you motivated to complete the course.

i have found no problems in this course and i actually liked it and the assignments were practical and easy to understand. Good Job!

PS. If i have payed for specialization, the "shortness" of this course would be disappointing.

Brilliant way of teaching HashMaps, HashSets etc. I've enjoyed this course the most out of the first 3 courses in the Duke Java Specialization. A big thank you to the course instructors for providing such quality material.

Understand that many peers get stuck in Week 1&2. But when you get through these, the course is very straight forward in week 3&4. And you should definitely read the comments in discussion forums. They are really helpful.

Really good course assignments and resources! I hope the lecture slides can be improved. The course is rigorous, challenging and intellectually stimulating. I hope Duke can offer more computer science courses like this.

Duke's Java programming class has been the best course I have taken for all other courses. I really enjoy the structure, the video, reading, programming assignments. I feel I am learning Java indeed for real use.

The professors had a way to just bring me down to earth in this course..Humbled me completely. the content was well organized .

the silver lining in this course was that there was less hand holding by professors .

The course is really well structured. The projects are interesting and the projects meaningful and challenging. The topics covered are very useful. Looking forward to the next 2 courses in the specialization.

It is great for Java beginner without prior programming background. But for those who have prior programming experience and seeking for a quick jump start to Java, there might be more repetition than expected.

The course is easy to understand and complete assignments. Rather than difficult courses, it is easy to keep on to finish it and friendly to a learner with little Java and programming knowledge.

Wow. This was a surprisingly challenging class. In the best of ways though. Some of the questions in the quizzes need some rewriting to clarify, but still very fantastic overall.

The homework is really helpful to master data structure in Java, while some of it is redundant. Learning this course takes more time than I expected, but it gives me a solid basis.

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

learned so much during this course. i never thought i'd be able to break the Vigenere cipher and i'm so glad that i was able to. thank you so much, instructors!

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!

Thanks professors from Duke University and this course for having me a chance to explore new knowledge about Java programming, specifically data structure.
