Implicits in Scala

 Implicits in Scala

Implicits in Scala are a powerful feature that can make code more concise and expressive. They are used to provide default values, conversions, and other behavior in a way that feels natural and intuitive. Here's an example of using implicits to provide a default value:

kotlin

object Implicits {

  implicit val defaultName: String = "John"

}

class Greeter {

  def greet(name: String)(implicit defaultName: String): Unit = {

    println(s"Hello, $name! My name is $defaultName.")

  }

}

val greeter = new Greeter()

greeter.greet("Jane") // prints "Hello, Jane! My name is John."

In this example, an implicit value defaultName is defined in an Implicits object. This value is then used as a default value for the greet method in the Greeter class. When calling the method, the implicit value is automatically passed in if no other value is provided.
