О курсе

The basis for education in the last millennium was “reading, writing, and arithmetic;” now it is reading, writing, and computing. Learning to program is an essential part of the education of every student, not just in the sciences and engineering, but in the arts, social sciences, and humanities, as well. Beyond direct applications, it is the first step in understanding the nature of computer science’s undeniable impact on the modern world. This course covers the first half of our book Computer Science: An Interdisciplinary Approach (the second half is covered in our Coursera course Computer Science: Algorithms, Theory, and Machines). Our intent is to teach programming to those who need or want to learn it, in a scientific context. We begin by introducing basic programming elements such as variables, conditionals, loops, arrays, and I/O. Next, we turn to functions, introducing key concepts such as recursion, modular programming, and code reuse. Then, we present a modern introduction to object-oriented programming. We use the Java programming language and teach basic skills for computational problem solving that are applicable in many modern computing environments. Proficiency in Java is a goal, but we focus on fundamental concepts in programming, not Java per se. All the features of this course are available for free. It does not offer a certificate upon completion....

Beautiful course. I am a software developer with 10+ years of experience in programming and have never realized depth of actual MATH behind all that I do. Thank you Robert Sedgewick, you are the BEST.

Can't wait to get into the second part of the course. The best programming course ever provided for free of cost. The techniques used are backed by mathematical thinking. It is just awesome.

This was a challenging course, but not for beginners. I am an experienced programmer in several languages and wanted to learn Java, which I accomplished. The course does not teach any design approach (such as flow charting or outlining), which would be best for beginners.

Good over all, but the quizzes can be a little annoying.

T​his review is really honest and based on my opinion and my personality trait.

T​his course is not suited for someone, like me, who hates math and did not do well with math.

S​ure, the programing is a true basic I understand the most and find with how it runs, but the reading material and assignment mostly have to do something with mathematic, which really hindered my interest, focus, and always made me feel burned out. Because at the time I am writing this review I am currently in week 3, I still can not do all the exercises in the reading material. It is hard for me. My knowledge of math is just a middle school, to be honest. It stops me from being productive and studying all the questions. And finally, I feel depressed. So, I decided to unenroll in this course.

A​gain, for someone who has a knowledge of math and likes it. I, sure, believe that you will be fine.

T​he only reason I find the first week easy is because it has less math than the second week.

U​unfortunately, I assume programing is out of my league. If only it involves less math, that would be lovely.

Lectures and assignments are heavily math-based, even in the very beginning, couldn't continue with course. I'm dyslexic and learning concepts using what feels like high-level math formulas and concepts doesn't work for me, couldn't comprehend a lot of assignment problem statements for the same reason. I'm sure it's great for those that don't struggle with mathematical comprehension, but it doesn't cater for those that do.

The course is not beginner friendly in my opinion. A lot of students, me included seem to be really confused about week 1's assignments, one can clearly see that in the forums. The class itself isn't bad, just advertised as beginner friendly. I do not find it to be so. Will retake it when will have a bit of basis of Java.

Challenging, but superficial. The lectures do a good job of giving big-picture overviews, but gloss over actual coding techniques and concepts. The weekly assignments are *miles* harder than what was discussed in the lectures. Often you will have no clue what the assignment is actually asking you to do. I completed the course by sheer determination, but I don't really know that I have learned anything that will stick, and it was a slow, painful process. I feel like adding more instruction video to really go over the concepts would help make this the best course on Coursera. As it is, this is a wasted opportunity.

Not for beginners at all. The assignments are for those whom have strong background in math and computer programming experience.

I really did try , I had trouble downloading the java. I try going to get help . then When finally get it right ,I try to do the HelloWorld assignment The path isnt there , So I deleted start all over again . download java and did assignment again , this time it take I am finally almost at the end on the command line . I close and go eat ,when I come back I got two assignment that are not mine in my folder wth and disable at the moment with my foot . working on computer for shop , and don't really have time to start all over so frustrating . I don't know what happen , I am mad and tired . i

Initial "introcs" program doesn't install properly because the Java compiler doesn't work - and yes, I installed as Administrator. Also, "DrJava" cant compile even the initial HelloWorld,java application used to test the introcs installation. It's not recommended to install manually because of all the additional plug-ins that are required or I'd fix it myself. It's a good thing this is among their "free" courses because I am certainly not going to pay Coursera to troubleshoot and fix their stuff. Unenrolled. Would not enroll again.

Your course is lacking the possibility to make contact with the teacher or helper, no e-mail, no telephone number. I am stuck on the learning process, I pass the 75% required on week 1 to go to the job assignment, the problem with the software IntelliJ, no possibility of help. Please cancel my subscription

A great course that is definitely not for beginners. I found this course to be an amazing resource in giving a solid theoretical basis to my programming knowledge. It is not meant to be as practical as Harvard's CS50.

However, some prior knowledge of basic programming and/or Java would be helpful, as not all features of Java are covered in the course and useful hacks programmers employ on a daily basis such as debugging by using print statements is not covered. In short, this course does not go through how to program practically, it expects you to pick that up by wider reading or by reading StackOverflow or Googling endlessly! I only survived because I used Google continuously, read sample java programs to understand how to code including the authors' own stdlib library), and improved my Java skills on HackerRank

Weeks 6-8 were really challenging, especially the one on recursion about Hanoi's Puzzle.

Great, well-designed course, with solid foundations on real-world applications that are really inspiring and enjoyable!

This course is really challenging for beginners, but if you persist with it you will definitely learn a lot. The instructor is a very experienced professor, so the videos are excellent. However, my main tip is to always read all the supplementary materials, including the book. Sometimes you will feel lost, but you will get a sense of accomplishment when you overcome those moments. Don't rush through the course; read each assignment specification carefully and you will learn. Last tip is to always check the forums if you are stuck because there are helpful tips over there. Like I said, this course is challenging, but in a good way.

This is an incredibly challenging course and is probably on par with first year university in terms of difficulty and independent learning and problem solving. I had no real programming and no math at all and this was insanely hard for me and I wanted to give up sometimes, but not impossible if you are a beginner it will just take a lot of work and time. The exercises and sample code provides is rich indeed and a great resource for further study and challenge. If you need something more guided and easier maybe try the Duke Java course(s) but if you can get through this, it is very rewarding.

All materials for this course are clear and concise. Aspects of Java programming were explained clearly in the video lectures. But if things needed a bit of extra clarity or I needed to refresh my memory on something the online materials were there for review. Programming assignments were explained well and reflected the material being taught. The automated grader gives good explanation of what is wrong with your code so you can make corrections and resubmit. I am planning on taking the second half of this coarse next.

For a newbie in programming, this course is highly recommended. It helped me to think in diverse ways. Having noticed java's rigidity compared to popular programming languages, i have been able to start with a disciplined approach by taking this course. I see things around me in a totally different manner during and after this course. It is also a pleasure having professor Sedgwick who smiles in his videos telling you its simple, I'm always like, professor, hope you know you got baby programmers in the class :)

A very demanding course, at least for me who did not know anything about Java and OOP, the weekly exercises are key in the process of learning and the Discussion Forum is very helpful to be able to pass the exercises. I have taken other courses in Coursera but definitely this is the best one on this subject honoring the fact that is taught by Princeton, where once I dreamed to make a PhD. Thanks to the University, the instructors and Coursera, I plan to take the next one that is recommended in the last lecture.

This is my first course on Coursera and this course is EXCELLENT. I started learning java in late 2019 and this course will make you a more sharp java programmer. If you do more then the assignments i.e. the web exercises and also using the book as ac companion with this course you will be facing challenging problems that bring joy if you managed to solve them.

Thank you Princeton University for making this course free and also for the grate Prof. Sedgwick and Wayne for building this course.

This course was incredibly helpful. I've taught myself Python over the years for data analysis purposes, but I never had a solid understanding of computer science principles like you learn in this course. Learning Java along the way was a nice bonus, and it was helpful to compare and understand differences across different languages. The projects were of an appropriate difficulty, and I would strongly recommend completing them so that you can practice what you learn.

I think the course has a great balance between introducing concept/history and practical matters. The only difficulty I encountered is that it is sometimes assumed that the students have certain knowledge (I personally spent a lot more time on w6 Recursion than other weeks because I found some concepts/knowledge unfamiliar). Overall it's a great learning experience that gives learners exposure to a variety of aspects of programming.

Well taught course, with minimal spoon feeding once it gets moving. I would like more baby steps through the initial Intellij install, as it was aggravating before I saw the value of the course. Being reminded early on that we all make mistakes (forgetting ; and the like) and that unfortunately compilers don't work because we yell at them helped me deal with the inevitable frustrations that come about during programming.

This course is the best. Big thanks to instructors. You can complete the course even if you never had similar course (in Computer science). The knowledge you get is high quality. Assignemtns are the most important in this course (as in any other course) and they are outstanding - especially the autograder that checks your work in detail and in detail reports your mistakes. It took me more time than ~ 9 h per week.

Definitely, this was the best course I've ever taken including my BSc and MSc education until now. Each assignment within this course is provided with the fields that they are most commonly used. I can not point out a single issue that was unnecessary within the scope of the course. I would like to thank Robert Sedgewick and Kevin Wayne for providing such a beautiful course with such a beautiful content.

A​nother superior course from Princeton's CS team of Sedgewick and Wayne. The programming exercises are challenging at an appropriate level and as usual, a generous booksite also supports the course with enough ancillary material to satisfy the ambitions of the most diligent beginning students. This is a course for new learners with a computer science bent and builds from the ground to a satisfying level.

Amazing course! It gives an opportunity to learn how to think about coding, how to approach real world problems and translate solutions into working programs in Java and other languages.

I sincerely enjoyed the course, especially video lectures and coding assignments, and plan to keep learning from professor Sedgewick and Kevin Wayne other courses on Cuorsera.

Thank you very much!
