How to call a function after a delay in Kotlin?

AndroidMobile DevelopmentApps/ApplicationsKotlin

Kotlin is based on Java, hence we can use Java-based library functions to delay a function call. In this article, we will be using a Java library function to delay the function call using Timer() and schedule().

Example

import java.util.Timer
import kotlin.concurrent.schedule

fun main(args: Array<String>) {

   // Execution starting point
   println("Hello world!!")

   // Delay of 5 sec
   Timer().schedule(5000){

      //calling a function
      newMethod()
   }
}

fun newMethod(){
   println("Delayed method call!")
}

Output

Once executed, the above piece of code will yield the following output −

Hello world!!
Delayed method call!
