Solve real world problems with Java using multiple classes. Learn how to create programming solutions that scale using Java interfaces. Recognize that software engineering is more than writing code - it also involves logical thinking and design. By the end of this course you will have written a program that analyzes and sorts earthquake data, and developed a predictive text generator. After completing this course, you will be able to: 1. Use sorting appropriately in solving problems; 2. Develop classes that implement the Comparable interface; 3. Use timing data to analyze empirical performance; 4. Break problems into multiple classes, each with their own methods; 5. Determine if a class from the Java API can be used in solving a particular problem; 6. Implement programming solutions using multiple approaches and recognize tradeoffs; 7. Use object-oriented concepts including interfaces and abstract classes when developing programs; 8. Appropriately hide implementation decisions so they are not visible in public methods; and 9. Recognize the limitations of algorithms and Java programs in solving problems. 10. Recognize standard Java classes and idioms including exception-handling, static methods, java.net, and java.io packages.
I was more diffucult than the previous three courses in the specialization, but all in all, I enjoyed it very much and learned a lot! Thanks for such a great course, keep up the good work! :)
My confidence level in Java programming has grown significantly since completing this specialisation. It gave me the necessary knowledge and practice I need to take up a role as a software engineer.
It's a very good course that solidifies your understanding. It gets challenging in week 3 and has to be done with great accuracy and attention.
Well designed and well structured with the packages, resources, programming exercises and practice quiz. I appreciate the team's hard work in delivering good knowledge on the subject efficiently.
The Course is Good. But Week 3 is so hard to understand and the assignments are frustrating and it took long time to complete. Week 3 must be made easier......
Amazing & superb Sessions given By all the instructor's on Java Programming .Happy With learning As well as get Important Knowledge by them
This course was another of many well-taught courses of Duke University. The GPS library use to find locations of earthquakes particularly of very interesting. Thank you Duke University
Super course!Well designed, structured, with a sense of humor :)To be specific, with this course you are able to write complicated programs step by step with linearly growing difficulty. Thanks!
This nicely packaged course is learner centered. It engages the learner by enforcing practice through interesting exercises and quizzes. Kudos and Thumbs up to the team of great instructors
A very challenging course with a lot of assignments, great professors and discussion forum. But I feel like the instructors could have given the instructions more clearly on the assignment
i liked everything except some of the quizzes since some questions were unclear or wrong (but still, I was a beta tester, so all great) - thank you!
In week 3, the Markov theorem should be explained more clearly. It was not clear enough to understand by only listening to the explanation.

A very simplistic and chaotic course. Explanations are all over the place.
BlueJ is probably the worst IDE I have ever seen and I have been a programmer for about 8 years.
There are far better courses. I would not recommend this course at all.
Beginning (course 1 in the Java specialization) was promissing but very fast the concepts became not understandable. Videos explain less and less but tasks become more and more complicated. In my opinion this course (and all Java specialization) is not ment for the beginners. This doesn't explain the most basic concepts a person that doesn't have IT background should start with.
The course is very poorly designed for begineer. This is the worst ever course on java
This was a great course, but it was very difficult. I am currently taking a 300 level Data Structures and Algorithm class in Java and relied on some things I learned from that course to help me finish this one. Still, I hit a few road-blocks on programs that held me back for a few weeks until I could find an answer. There were times where I wasn't sure about the specifications. I also needed to use Eclipse on the final program to help find some errors. I spent between 10-20 hours per week on this course. It would have been very helpful to go through the course with someone or a group or have a person that I could email a copy of my code to for suggestions. Overall, I am really glad I took the course. I learned a lot!
Super course!

There are a large number of people requesting help with the content in week 3 of this course. Many of them state the assignments need clarification, while others have made significant progress on the assignments but are requesting additional help understanding. Few of these threads in week 3 have been addressed, and I notice many of these threads date back for up to 2 years.
I have subscribed to this course three times in hopes of persevering, but I can't justify spending any more money when so many students are receiving no replies when asking for help.
thanks for the course, but
-your quizzes is real pain, some random variable could cause wrong result
-your should follow how it is implemented in lectures in stupid way, like "efficient" way when you build hash map N^2 instead of N
-bluej sucks you make a lot of clicks to run method, use some decent IDE like eclipse or idea
My confidence level in Java programming has grown significantly since completing this specialisation. It gave me the necessary knowledge and practice I need to take up a role as a software engineer.
Pros: The programming assignments were really great
Cons: The video lectures were not enough to understand the concepts.
Tip for learners: Do some research (like watch some youtube videos of the related topics, read geekforgeeks etc ) before watching the lectures.
Many of the assignments in week three were incredibly hard to understand and required scouring the forums to locate where other classmates had to beg instructional staff for assistance. In many instances, the staff agreed that the course had many shortcomings that would be addressed in "upcoming iterations" of the course. However, many of these posts were made up to three years ago, so it made the student feel that not only did the class have errors that the staff did little to address for new cohorts, but also that the updating of the curriculum is not a priority and therefore that the class is now an afterthought.
The practise quiz and weekly quiz are always repeated and tedious, You need to test your program on data of different types/ranges, but not the same taype/range. It has no meaning.
Plus: The estimated time for doing the programming exercise showing on the course page is not true. Even for an experienced software engineer, sometimes over 2 hours for debugging code in the assignment is needed. It took me 4 full days of 10 hours per day in average to finish the course.
Overall this course is better than the previous 3 courses of the specialization.
Es muy interesante el curso, pero ... la forma en que se plantean los problemas muchas veces no me fue clara, porque? no entendia que recurso debía obtener, muchas veces no podía avanzar porque no me daban los mismo resultados en los ejercicios, pero si estaban correctos en las evaluaciones. Mi mayor desafía fue en Markov no entendía lo que pidieron y mucho la lógica a trabajar, no la lógica del algoritmo, sino la del curso. Veía que habían muchas preguntas sin resolver en el foro por parte de los alumnos
Excellent course, the best I have taken so far. The lessons and assignments are very well designed for you to understand fairly advanced topics. The quizzes are entertaining and engage you with a lot of debugging. Best of all are the contexts around the issues and the narrative of why this or that is a good strategy to implement. Many thanks to Rob, Drew, Sussan, Owen, and all the Duke U staff. I recommend it to anyone.
pretty good, week 3 was challenging for me and the concepts of interface and so on. but in my opinion it should be this way for the learner to have problems and try solving them. Discussions were always helpful and am looking forward to the object oriented programming from San Diego university
These set of four made not only learning Java fun and also explored on the applications software engineering it has on the real world, touching a little bit of everything in the same field.
Like all the modules of this Java specialization, the teachers are very good and the course reaches the objective of teaching the fundamentals of software design with an excellent didactic.
Este curso es muy bueno, no es para empezar de cero, pero si para aquellos que tienen un poco de conocimiento y quieren empezar a entrar al mundo de la programación en Java.
Software Design Engineering, Programming, Debugging, to be Patience and Consistency
Very good info on software.
