Kotlin for Java Developers from Udemy

Are you a Java developer wondering if you need to learn Kotlin?

Maybe you are an experienced Java developer who wants to learn Kotlin quickly, to be prepared for future project work.

Perhaps instead, you're an Android app developer who knows Java well, but you want to be able to move forward with Kotlin for new Android development work.

Well, with Google's recent focus on Kotlin for Android app development, this language has been launched into the mainstream, and you can be sure you will be seeing a lot more about it. It's also highly likely that you will be working with Kotlin in your Java projects in the near future.

Because Kotlin works anywhere Java works, and can even be called from Java code (and vice-versa), this brings with it a massive opportunity for Java developers. Being able to work with both Java and Kotlin is going to give you a massive advantage over other programmers.

This course was designed to teach Java developers how to use Kotlin in the shortest possible time.

Sarah Ettritch, your course instructor, is an experienced Java and Kotlin developer, with many years of software development experience. She is uniquely qualified to teach you how to use this powerful and exciting language.

While you won't learn Android app development in this course, you will learn Kotlin, and also the key differences between Kotlin and Java.

There is an entire section dedicated to Java interoperability, which is vital for all Java developers to learn.

In addition, the Kotlin syntax is explored in detail.

Over sixteen hours of videos are included in the course, making it one of the most comprehensive courses on the language.

Now is the perfect time for you to learn Kotlin, while it's relatively new. It has been around for a while, but only now is it being thrust into the limelight.

It's absolutely vital for Java developers to learn Kotlin to maximize future career opportunities. Objective-C developers who failed to transition to Swift, or were too slow doing so, were left behind. Don't make the same mistake they did.

If you are ready to greatly increase your career prospects by adding Kotlin experience to your skills and knowledge, then sign up for the course today.

Reviews summary

Kotlin for java programmers

According to students, this course offers enough context to new concepts in Kotlin for those already familiar with Java and C#. While reviewers say that this course was helpful in getting up to speed when joining a team using Kotlin, the lectures may be more suitable for those with some prior experience with Kotlin or object-oriented programming in general.

Helpful for understanding the implications of having Java call Kotlin and vice versa.

"...It has been good to understand the implications of looking at how Java can call Kotlin and vise versa as I expect to be running into more of those challenges in the future."

Good course for transitioning from Java to Kotlin.

"I joined a team using Kotlin in the last two weeks, and this course has enabled me to get up and going and understand some of the things that initially seemed weird about Kotlin."

May be more beneficial for those with some prior knowledge of Kotlin or object-oriented programming concepts.

"I felt that there was enough context to new concepts...to understand what they are for, when to use them and why they are beneficial."
