Kotlin Generics

Kotlin Generics

Learn and implement generic functions and classes in Kotlin.

We'll cover the following...

Kotlin generics allow us to create reusable and type-safe functions, classes, and interfaces. They provide a way to define placeholders for types, making our code more flexible and adaptable to different data types. Let’s cover the basics of Kotlin generics, generic functions, and classes.

Generic functions

A generic function can operate on different types without sacrificing type safety. We can declare a Kotlin function with generic type parameters using angle brackets (< >). Here’s an example:

Press + to interact
fun <T> printItem(item : T) {
    println(item.toString())
}
fun main(){
  printItem("Educative!, a learning platform") 
  printItem(786) 
}
