Why is Kotlin better than Java?

Kotlin was designed to replace Java, so why is it the superior programming language? Lead developer, Andrey Breslav, explains how Kotlin is designed to deal with bugs by removing them entirely from the ecosystem, something that he says cannot be easily done with Java due to its age.

Interview conducted by Dr Tom Crawford (University of Oxford) at JetBrains HQ in St Petersburg, Russia.

Very diplomatic of him to not mention Scala 2 vs 3 in this context ;-). The nice thing about Kotlin deprecations is that they play nice with the IDE when it comes to fixing them. I recently auto fixed deprecation issues when upgrading okhttp to v4 (the complete rewrite in Kotlin). The whole process took me a few minutes.

Hi Tom, I have taken a course from Udacity on Android Development using JAVA and i have successfully created my first app using android studio with some basic Java code, Do i need to dive more in Java before i start learning kotlin or i should continue learning Java first? I just want to progress fast!

Unmasked Kotlin. What you will see is Java

[HtopSkills]

Kotlin is my favorite programming language

Making the lack of checked exceptions support into one of the greatest features makes me very sceptical about Kotlin and their maintainers. Just support it and let people decide which trend they follow. We're adults.

which java android and kotlin android is better in 2021

[bahabaha]

The vidoe does not respond to the question

Nice video but the title and teaser are just wrong.

Ok now explain what the different of array and arraylist in kotlin.

[gopfertami]

Really is better? It has some nice features but partially it’s spoiled java ;).

[neerajverma]

everything behind the scene will be converted to java, Note- kotlin is larger, complex language

[jursamaj]

Kind of annoying that he makes sweeping generalization without specific examples.

"We do long deptecation cycles..." Okay, with you here.

"Python is a disaster." You lost me here. What do you think Python 3 was? A long deprecation cycle. Just because it's not what you want doesn't mean the language is a disaster.

[CodeWithCal]

Talks like he invented depreciation 😆

Google has backed kotlin therefore it's the future for Android app development.

But so far nothing about the project has won me over. Personally the null safe stuff is just there to cover for programmer but can be also be a nuisance
