When I signed up for this course I had already taken a year's worth of Java classes and was quite well prepared. My overall opinion of the course is that it was really good and the instructors did a good job by presenting clear videos of some beginning - intermediate level concepts. I especially liked Christine's and Mia's presentations. The videos on memory models were really great and helped me a lot. The assignments were really interesting too as they collected and mapped real time data of earthquakes onto a map, but some of the external libraries being used in UnfoldingMaps could have been explained a little better as to what their implementations were. In the beginning it was a little confusing trying to figure out the superclasses even though the Javadocs for them were available. I also felt that the Interaction Design Lab in Germany - the folks who implemented the UnfoldingMaps could have made the Javadocs of their classes a little more detailed. Further explanation of how to use the classes built into the course would have been very helpful. Hence the 4/5 stars given. But overall I really enjoyed the class and am really looking forward to the second class in the sequence. Well done!

Good course, ideal for the first half of a second course in computer science. A little java experience is recommended buy you'll probably be ok if you have program in a statically type programming language before because you can pick up java very quickly. The lectures are very good, I think that the teachers are excellent expositors but I feel that they could be more detailed. The project is about representing earthquakes in a map and you are always increasing the complexity. Finally you need to add your own extension which I found an excellent opportunity to test your imagination and your capacity to create new things.

The only cons of the course for me is the way assignments are evaluated. I think it has to do with the fact that they are interactive. You have to answers questions in a Quiz related to the week content and the project. But the are not very demanding, therefore they do not reflect how much you really know.

In general I recommend taking this course if you are in self study journey in computer science, even more the specialization start to get more interesting and demanding in the follow up courses, more complete and detailed.

It was a good course. If you are looking a general introdution to Computer Science with Java elements, then go for it. My intent was to simply go over syntax and some intricacies of Java. It is slowly paced in this manner. Nevertheless, I've completed a 6-week course in about a week (not working everyday) and managed to get a certificate.

The structure let's you skip things you already know (like searching algorithms) and implement stuff on your own. One thing that they could have addes is ... code checking. A self-validation is not good when it comes to veryfing real programming skills. However, I guess Java grader would be more complicated than already existing coursera's python grader.

All in all 4/5, could be better, I don't think Java itself was the main focus of this course. Good very intro to the topic.

Although I agree that the mapping library that is used for the programming assignments adds something visually interesting to the course, I felt that it added an unnecessary level complexity when it came understanding the object-oriented aspects of the language. I spent a lot of time trying to understand how to use a library that I won't likely use again just to be able to apply the core programming concepts being taught in that lesson. Having said this, I felt a good sense of accomplishment after getting through the final project.

I have been following this course since mid 2015 and I found it very good. But because of my busy schedule I usually switch the session. But this time I am really motivated to devote some time for this great course to learn OOP. I have learned a lot in my university about java programming but they did not teach us these stuff which are practiced. we solved a lot of problems there but they had nothing much about using java libraries and OOP. Thanks all the lecturers from UCSD and Coursera for such a great course.

This Course was great, and the instructors are engaging. The layout of the course is really great, the various paths that one can take through the course is a plus. For those starting out learning the material the first time or those who are experienced and just want a certificate, this course offers a great layout to choose your own path. I enjoyed this course a lot. I came from the Duke University course here on Coursera. This course was simple enough to understand and get through after taking that course.

The only complaint I have about this course is the horribly irritating music at the beginning of each lecture video. I would have my headphones in, volume up so I could hear the lecturers clearly, then when the next video would start there would be this terrible music that started very abruptly. If I was very quick I could mute my volume until it finished, but I think this is totally unnecessary. PLEASE consider changing this, as it will affect my decision to pursue further courses in this specialization

Core concepts of OOP are explained very well in this course. Assignments were quite practical in nature and implementing them was challenging and fun. I would recommend the course to anyone who wants to strengthen and formalize their knowledge of OOP concepts.

I wish assignments would be submitted for code review and students would be able to get more specific input from mentors on code organization and style. Integrating with github would be a great step forward towards transparency as well.

Coursera gives Universities the flexibility to show their own style of teaching and sharing knowledge.

I really love this course, good project.

However, good course is not only the instructor's' responsibility, but also the students' active involvement.

I rate 4 because we need more students get involved in developing this course like creating wiki notes.

Extra material to read etc.

Its a good course to take. As we learn OOP in a better understandable way. Instructors explain the concepts well. Also I always like working with maps and as this course assignments are based on map data, plotting data on real maps it like it more. But it would be great if the course have taught to execute the same code through java jar. As using Papplet via eclipse is easy but how to use the same code via computer terminal is quite tricky as we don't find any main method in our code.

Some of the questions are not Java related ones at all which I couldn't see much of a helping point, e,g. What are the coordinates of rio de janeiro?. There were also a few of questions that I found a bit confusing because the code provided is plain white and it's a bit hard to focus on it. I'd rather want to customize the color of the presented code just like modern IDEs do. Everything else seems rather okay and intuitive. So far so good, guys :)

Great introduction to Java. Gives you an opportunity to play with several different libraries from the start, rather than learning the basics with just text input and output like most courses, which is really cool. No peer review, just quiz questions that can only be answered if the assignment is completed correctly. The assignments are therefore not particularly challenging -- you get out of this class what you put in!

This is definitely one of the best courses I have taken. The presentations, resources, and projects are very creative and well designed. The "what do you want to cover next" quizzes tempt you to try things on your own before looking for help, which is a nice teaser. The only reason I give it 4/5 is that a few of the project instructions were too vague to figure out what they were asking for (i.e. without asking).
