Is Kotlin different from Java?

It is a perfectly good option as long as you don’t neglect the need to understand the concept of coding thoroughly. Kotlin allows you to start coding quickly and to obtain fast results, especially thanks to all the available tutorials and examples for Android – if this is the area you want to pick.

Kotlin does not have a new keyword . To create a class instance, call the constructor just like a regular function. We saw that in the screenshot above. Kotlin has single inheritance from a named superclass, and all Kotlin classes have a default superclass Any , which is not the same as the Java base class java.

0 Kotlin 1.5. 0 introduces new language features, stable IR-based JVM compiler backend, performance improvements, and evolutionary changes such as stabilizing experimental features and deprecating outdated ones .

In Kotlin, we can use the @Deprecated annotation to mark a class, function, property, variable, or parameter as deprecated . What makes this annotation interesting is not only the possibility of deprecation, but also of providing replacements with all the necessary imports.25 Eki 2017
