The Kotlin programming language is a modern language that gives you more power for your everyday tasks. Kotlin is concise, safe, pragmatic, and focused on interoperability with Java code. It can be used almost everywhere Java is used today: for server-side development, Android apps, and much more. Kotlin is 100% compatible with all existing Java frameworks, and has good tooling support. It’s a pragmatic language with a very low learning curve, and can be quickly grasped by Java developers. Kotlin code might be compiled not only to JVM bytecode but to JavaScript and Native code as well, but this course is focused on Kotlin/JVM.
This course aims to share with you the power and the beauty of Kotlin. We'll have a basic overview of the language, as well as a discussion of many corner cases, especially concerning Java interoperability. The course is based on your Java experience; it shows the similarities between the two languages and focuses on what's going to be different. Note that this course won't cover the programming fundamentals. We'll discuss: basic syntax, nullability, functional programming with Kotlin, object-oriented programming with Kotlin, the power of the Kotlin standard library, and Java interoperability.
User review:
Course is an awesome starter for a deep dive into kotlin. Lectures material is great. Assignments could be improved though. Descriptions of certain tasks was a bit cryptic. I had to analyze test cases to figure out what actually needs to be implemented and those tests cases are not complete either had to add more when intergation ones failed.
Here is an example of what I mean from the last week assignment: "The board for the game of Fifteen is filled randomly with numbers from 1 to 15 and one empty space. " Here sounds like word "randomly" also relates to the empty space e.g. we should put space at random possition between permutations. This is exactly what I did, I also played the actual game implementation provided and it works the same way e.g. when you shuffle space is at random position. So my implementation seems correct, but all the tests fail. Why? Because in all the scenarious there is an assumtion that empty cell is always the last one so I had to rewrite the logic to match tests. [1]... Read More

User review:
I think the course is amazing because whether than teach theory it dives into writing applications. A lot of people pointed out that they are confused and stuck, but that is what writing real applications is like. You have a task, you have some idea of how to do it, and then you use all resources at your disposal to get it to work. It's not pretty but that's what learning is!
The one issue I have with the course is that the lecturer often does explain WHY we do something. The WHY tends to be learned after a few iterations of doing something rather than being explained at the start. I'd really have liked to see him use analogies and examples to solidify concepts rather than stating "well, it's complicated and it's boiler plate code anyway - so moving on" [2]... Read More

User review:
This course is on the longer side of things, so beware before you jump in. My advice for consuming this material is do a bit every day and keep chipping away at it. Make sure to do the challenges and it's useful to reinforce your knowledge by going back to the previous apps and adding in the methods you learnt as you progress. After all programming is problem solving so going back on your own will help continue your growth as a programmer.
Onto the review, the information is clear and very detailed. As a Software developer looking at learning another language to my arsenal, there was a lot of information that I already knew thus I could 2x speed the videos. I wouldn't say this as a negative as someone who isn't as familiar with code would find this information extremely valuable!
Overall I am extremely happy with my purchase and I'll be moving onto looking into more advanced features as well as enhancing the skills I learnt throughout this course.
Thanks Tim! [3]... Read More

User review:
Well, i am giving 5 stars to Peter because he covered a lot, from the ground up, and also, the fact that Peter provided challenges and quizzes - in my opinion - makes this course stand out from others. It really helps to digest the lecture and really sink it in. I feel like i can actually start coding in Kotlin after this course. There was one thing though, which overshadowed the impression... Well, when Peter got into math, binary, hex, etc ... my eyes crossed and i lost 3rd part of the brain i had... (was not much to begin with lol). But, really, if you are just starting with development OR even if you know a bit but want to learn Kotlin from complete scratch - I personally believe this course is it! Thanks Peter! [4]...

User review:
Thorough! I'm an experienced programmer, so I'm a bit biased currently, because I'm already familiar with a lot of the concepts, which make it easier to move through the material. The instructor makes it very clear up front that he'll be focusing the language features in depth. I also get the impression that examples will not be overly complicated, yet complex enough to demonstrate the use and effectiveness of a language feature. There are places where I would have welcomed a discussion about an actual code examples, rather that hearing about the key features and rules about an area of the language. Because of this, I would welcome more code examples during discussion and more code along exercises spaced throughout the course. For example, there are many subtopics related to object oriented programming and discussed thoroughly, but the experience was not broken up with some coding, so I lost interest at times. [5]...

User review:
I 've been following Sriyank's courses and lessons some years now. And always was a great experience. An Android developer myself found in Sriyank's courses not only how to do something but mostly how to do it the correct way. After Google announced that Kotlin is an official language for Android development and having to do an Android app for my Msc dissertation, I thought why not to use Kotlin. I searched for some books and online sources until I found Sriyank's Kotlin Programming course, and immediately my searching stopped. I knew that it would be good... I am at the middle now and I wasn't wrong.
Congrats Sriyank and I hope to add more videos, specially for Android development! Thanks! [6]... Read More

User review:
I loved the course, and JonnyB is such a good teacher. There were some problems I encountered along the way, particularly with things that have changed since these tutorials were made. It meant I had to google / watch youtube videos to learn how to do the updated stuff, and then resume watching the tutorials. For instance, using MongoDB. The one JonnyB used had been deprecated, so I had to research how to use the latest version of it. Similarly, one of the assets folders for the DinnerDecider App wasn't there, so I had to make my own images. All of the above was a good learning experience, as it meant I had to problem-solve before I could continue with the course. This was my first Udemy course and my introduction to Android and Kotlin. I'm a coding newbie, and although there were many parts of this course that went totally over my head, it gave me a good overview of the kind of things that Android Development entails. This course has helped me to understand some basic Android concepts, but now I need much more practise at applying them. [7]... Read More
