Out of date material that leads to a lot of errors when trying to do the assignments on current technology. Very unfortunate. The only positive is that you can still watch the videos for the theoretical aspects.

절대 듣지마라. 동료평가 때문에 짜증난다. 일주일 무료라고 해놓고 3일전에 다 끝내고 동료평가 기다리는데 최소 4일은 걸린다. 공짜로 듣는 사람은 일부러 매치를 못하게 하거나 하는 알고리즘이 있는듯 하다. 아니면 듣는 사람이 별로 없는 인기 없는 강의거나. 둘 중 하나겠지 ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ

The course materials seem to have been made over 10 years ago(on Java 6) and there doesn't seem to be a way to run them anymore.

I was trying to install the outdated JDK 1.8 that this course forces me to use, spend 4 days, learnt nothing. Do not recommend.

Course is outdated. things you learn are not supported in latest version of java.

Lecturing is alright, but why are we still using applets to teach?

The course is outdated and boring

reallly old

I would give additional stars if it was possible. Some prior programming experience is required (I think they already specify this as a prerequisite). That said, if you just done basic programming but never used GUI libraries before, this is THE BEST POSSIBLE INTRODUCTION to using libraries.

Must say a word about the course structure, material and the professors. They are all, yes all three of the professors, in one word: AMAZING!! Their tone is encouraging and it is a privilege learn from them.

The course structure, again 5 stars. A combination of the CORE and concept challenges cleared up any muddled up concepts in my head. So analyzing and understanding the support code was a breeze (it took me multiple attempts and umpteen reviews of the videos to get this far in the course but I am definitely more knowledgeable and competent than before I started)

The course material is really good.

I am highly motivated to complete this course and go for the next one provided by this dedicated team of fantastic teachers.

This was an excellent course in Java programming. My entire programming experience prior to this course was my own reading of Java basics from tutorialspoint.com. So, basically little to no experience. With this being an intermediate course, my learning curve was quite steep. But the 3 professors have done an excellent job of creating an interactive and challenging learning experience.

The lectures are engaging and on point. I love the format where they tell you an overview of the assignment ahead of the week's lectures. This way, you can associate ways of using things learnt in the lectures while you learn them.

I also loved how the assignments built up from being quite easy to very challenging over the course. Each passing week uses skills acquired from all the preceding weeks, offering a nice continuity that aided my learning. Overall, my entry into programming was made thoroughly enjoyable through this course and I'd like to thank the team that created this course for it.

A great introduction to core object-oriented programming concepts like abstractions, inheritance, and polymorphism. The best part were the 'Concept Challenges' with UCSD students walking through their thought process. The practical project work in Java is very rewarding but is a bit dated (Applets have been deprecated since long, so the GUI concepts could use an update) but the concepts used in the projects will let learners apply it to any library when building modern projects.

The peer-graded assignment section was pretty creative but the feedback received from fellow learners was pretty weak and it seemed everyone was in a rush to just complete the course and get a certificate without taking the time to build an extension with new, exciting functionality.

Great introduction to OOP with Java. This is not a pure theoretical course, neither a entirely practical course... It is both, so the instructors present the material with a good balance between theory and practice. Part of your assignment tasks is to explore on Java classes and learn how to use their methods (functions) in your own programs, which gives you a taste of a daily programmer job. The end of course project stimulates your creativity!

Nonetheless, this course will be challenging for someone who has not been exposed to any OOP concepts before. Make sure to practice a lot and go to the discussion forums, which are a great resource for help, at any moment you need it.

Amazing course with really thoughtful content. I absolutely love this course and have learned a lot from it since challenging concepts in OOP have been taught in a very entertaining and effective way. After this 6-week course, I'm sure you should be proud of how much you have learned and accomplished. My biggest takeaway from the course is how to trace code and draw the memory model to understand the code. Thank you so much for such a great course! I would definitely recommend this specialization in general and this course in particular if you want to brush up on and gain in-depth knowledge in Object Oriented Java Programming in an enjoyable way.

I was struggling in my CS Master's when I found this class.

I'm now a Software Engineer at Google.

I think this course is one of, if not, the best you can find in Object-Oriented Programming. I really appreciated how the course was shaped for industrial standards. You will learn how to read the real Java Documentations, how to implement your code in an existing code base while also learning the fundamentals of low-level programming language.

I'm also very grateful about the financial support I was granted, now it's time to give back :)

Thank you, Mia, Christine and Leo for your help!

This course is my first formal course on Object Oriented Programming and I enjoyed the course and the assignments. Yet, I have to say the course assignments are quite difficult and it will take more than expected to complete them. So, this course is not an easy one and the last assignment is especially difficult to complete but in turn, it is chellanging and fun. After completion of the course, I have a better understanding on the Java concepts in Object Oriented Programming and started my use of Eclipse as IDE tool. So, the course may not be easy for new learners, it is FUN.

This was a good course - I finally understood polymorphism and inheritance. The lecturers really went deep on the way the constructor works and so on with good clear examples. I also liked the projects - they felt really practical. I just disliked the casting that is used everywhere - I am pretty sure that's not the best practices to cast all the time and instead is better to structure the code differently. But I am still a beginner and I learned a lot here!

It is good to bookmark the three or four critical videos and just re-watch them later when I need to refresh some concepts.

Before starting this course I was reading (not completaly) a few Java Core books and was making interactive exercises on the web.

This course turned out to be not so difficult as I thougth before starting, but it is very useful! First of all cause it bases on two helpful Libraries for Java: UnfoldingMap and Processing which give you a hand with building your own app at the end of course.

So i got perfect expirience to making my own Java application by using external Libraries and became more confident in my abilities. Thank you teachers and see you in th e next course!

The instructors are clearly very passionate and skilled at teaching. The course is well structured. They combine lectures, quizzes, concept challenges, real-world examples, extra support videos, sample code, etc, etc, etc... altogether, it's an effective and supportive learning environment. While the exact technology being used here is quite outdated now (Java version 8, Applets, etc), which makes the initial IDE setup quite difficult, the positives outweigh the negatives, and I definitely recommend this course.

Very good course , really wonderful instructors , who could deliver the content in a very very professional way .Also , they could help me with the OOP concepts like inheritance and polymorphism in a great way . one more great topic that they touched on , was the algorithm part , this was so important for me .. and they made it so easy for me to understand and think in terms of proficiency and optimum solution . Thank you so much professors for this wonderful content and the professional way you handled it .

Excellent course. Some courses that are "object-oriented" start with simple variable declarations and they are extremely boring to work through as there is very little progress in each week. Others assume you know a lot and they are very confusing. This one is very good if you have been exposed to programming before and want to learn object oriented approach. It isn't too easy or hard. Instructors take the time to explain concepts rather than simply using them. Highly recommended.

Excellent course! The object-oriented programming concepts are explained in very depth and also examples of how to use those are shown. Here I got a hands-on experience about how to design working software and connected different parts to make it a usable software. What I liked most is that this course had some motivational videos to keep the student motivated. I am very thankful to all the instructors, the team helped to make this course and the UC San Diego.

This course is one of the best programming courses/resources I have used. Most will only teach syntax, especially for those at a beginner level. This was the first resource I found that took the syntax knowledge and showed me how to use that to actually create a useful application. For students at that awkward level where they have learned enough syntax to make basic small programs but can't figure out where to go from there, this course is absolutely perfect!

Great course! I highly recommend it. Topics very well handled. Perfect evaluations, carefully thought through. The only thing that I would change, is making the pier-reviewed final part optional and non-graded, I had to wait several days to get enough reviews to get the course completed, and from experience in other moocs, peer-grading sometimes is a bigger problem than that. I already started the next course in the program, loving it so far as well! Cheers!

The course is insightful and intuitive. The professors have done a great job. If you are already a programmer in some other language, you might find some topics a bit primitive but the project that is at the end of the module should be a good exercise even for the experienced programmers. And, to recreate the entire project on your own would be a great exercise. It will also gear you up nicely for the next course in the specialization.

Good course on object oriented programming. The topics are well organized and presented.

The only small problem is the Java application that needs to be worked upon for the course exercises. It is based on applets and needs Java 8, which lead to challenges in setting up the development environment for first time learners. It would be better if the course material was updated to use an application that works on recent Java versions.
