Excellent course, love it.

Awesome beginner's course

Great stuff for beginners

Excelente mucha practica

Divertido e interactivo

Amazing

Es un buen curso si eres principiante en el lenguaje, explican todo lo b谩sico del lenguaje (sintaxis, ciclos, clases, abstracci贸n, encapsulamiento, interfaces, etc) de manera clara y sencilla y las pr谩cticas son bastante did谩cticas y te llevan de la mano, algo molesto es que en algunas de estas debes hacer que la salida coincida exactamente con la que el sistema de calificado autom谩tico quiere, lo que puede llegar a ser molesto. El entorno virtual utilizado es un poco lento, estar铆a bien que te dejaran hacer los c贸digos de manera local en tu escritorio y subirlos cuando los tengas hechos.

It was a difficult course, not all explanations were catchy, I think that examples could be more simpler. Also there were technical issues, such the dessapearing subs under video and I am struggled in first lab. I work in mac and needed to use for switching keyboards. However, I'm very pleased for a lot of practical code assignment, because Java is a difficult language and for comprehensive understanding of Java principles you need practice a lot. I hadn't made any code in Java before this course, now I can create something. So, I think the course is nice. Thank so much!

Muy buena explicaci贸n, solo al final el ultimo laboratorio en la creaci贸n del Zoo le falta un poco m谩s de detalle en algunas instrucciones o alertas para coordinar la salida esperada, puesto que si falta alg煤n punto a la impresi贸n o se edita m铆nimamente el texto, pero tiene el mismo significado, lo toma con un error directo.

Un curso bueno, interesante, muy completo y con ejercicios practicos que te ayudan a entender mejor. El unico problema que le encuentro es que es un curso muy dificil si no sabes nada de Java o entras sabiendo muy poco, el curso es algo denso para un principiante

Last module is a bit scuffed since you need to get the same results as the Emulation which is confusing since variable names can be different and they do not share how you should name your variables

The course is great overall, except that some of the questions' instructions don't align with what the 'grader' expects. It looks like some of the instructions in the questions are outdated.

Some of the assignments specifically the coding assessments are missing the code sections on the instructions page. Otherwise this is a very good course would be a 5.

It would be ideal if the course were in other languages. In addition, there are some errors in the statements that are clearly left over from previous versions.

The Overall Course was absolutely great. But the testcases for final assessment were not clearly mentioned.

Information was helpful and mostly clear, the grading on the the final lab is a bit finicky.

Inconsistent instructions and some examples don't even match the instructions.

Need subtitles on spanish!!, but all ok

The instructor was incredible and explained everything clearly and with a lot of examples. My problem with the course was how unpleasant the experience with the lab exercises were. The environment was slow and the projects sometimes repetitive and dull.

A lot of typos, even in quiz exams... Also at one point some important syntaxes are skipped, while sometimes the narrative in videos are so childish. Had to google myself a lot and read Oracle's documentation.

(Note that this is an online course that is months old at the time of review and that it may be updated)鈥ㄢ�� Easily the worst learning material I've encountered (free or paid) on the subject of programming. These complaints extend to the second course in the Amazon Junior Software Developer specialization up to the first module (where I've decided to quit after seeing the syllabus and content don鈥檛 line up). As someone who has explored a number of object-oriented languages, learning Java should not be challenging. The actual difficulties come from tolerating this low quality course as someone pressed for time and presumably paying for quality. Consistency feels like the root of the problem. 鈥ㄢ�═rying to bear in mind that someone with no programming experience will likely take this course, I commend Amazon for belaboring every concept to - the point of absurdity. That鈥檚 consistent. There should be a world record awarded for how many permutations of 鈥渨hat is polymorphism鈥� they could pack into a single course without actually adding anything substantial. To do this with Easy-Bake oven style labs that in no way resemble a real-world, useful program is unavoidable in beginner material. That鈥檚 fine per se. A solid foundation is key.鈥ㄢ�� However, couple this very low expectation of the novice鈥檚 ability to comprehend a concept with the apparent requirement that the novice will wander through hundreds of pages of dense language and virtual machine specifications as well as APIs to pick up on random nuances of the language they will be graded on without warning. That鈥檚 not consistent. Videos, labs, and reading assignment don鈥檛 feel like they鈥檙e mapped to graded tests and quizzes properly. To make it worse: there are no satisfying wins that motivate you to keep going which should be the hallmark of exemplary educational material鈥�.and you will need some serious motivation given all the faults I鈥檝e encountered. 鈥ㄢ�∣ther courses I鈥檝e taken on similar languages have you create full blown, networked, multimedia applications within a very short time with good pacing and supplementary materials. You will still be producing basic print statements* in labs of the second course after this one. 鈥ㄢ�═he labs are the worst part. Every new lab will induce increasing dread whether or not you鈥檙e a total novice. 鈥ㄢ�═he environment is pretty nice, but the content will haunt you. How does carefully going over the instructions only to find out the explicitly expected text across the entire program is counted as incorrect sound? Symbol names patterns? They鈥檙e not consistent in the instructions nor do they match what is expected when the lab is graded. The resulting errors you should look to for guidance? They鈥檙e truncated and verbose output from a bespoke automated grader which issues random tests, meaning you鈥檒l spend an hour retesting and fixing punctuation requirements you can鈥檛 anticipate. 鈥ㄢ��*Whether every beginner鈥檚 educational Java program should be restricted to outputting print statements in an emulation of a terminal emulatior is a moot point. How does the lab introducing a code instruction that only make sense in a vague graphical context sound? You weren鈥檛 shown any APIs related to graphics. A no point were GUIs mentioned, but the lab is going to insist that you think hard about how the obviously graphics-related code fits into the final lab solution鈥�.which doesn鈥檛 even utilize the code in question. With the lab scenarios being as comically contrived as they are, the complete lab code is exceedingly sparse. For there to then be extraneous, irrelevant code is a problem and inconsistent. By the time I encountered this error, I was already conditioned to poor lab quality and just assumed there would actually be graphics added to the lab in a module that isn鈥檛 about graphics and hasn鈥檛 been preceded by anything graphics related. That tracks.鈥ㄢ�� Okay, you鈥檝e learned a concept, applied the concept, have be tested on the concept, and then did basically same thing with minor grains of novelty for 4 modules straight. Good job! You鈥檙e pretty robust and resourceful making it through all that. Take a look at the syllabus for the second course. Error handing and file handling starting in module 2. Nice! New content! Wait, it's actually another 4 modules that rehash the last 4 modules of the previous class because we have to be sure you haven鈥檛 forgotten what an object in Java is. (Update: at the time of posting, it looks like they updated the second course to actually reflect the syllabus but I鈥檓 not sticking around and paying for it. Never should have been an issue to begin with considering I鈥檝e paid for a complete course, not a half finished one that's being revised actively).
