How to create a countdown seconds timer in Kotlin

Answer 1

import kotlinx.coroutines.*

fun countdown(seconds: Int) {
    println("Total time: $seconds seconds")

    var remaining = seconds
    while (remaining > 0) {
        Thread.sleep(1000) // Sleep for 1 second
        remaining -= 1
        println("Time remaining: $remaining seconds")
    }
}

fun main() {
    val sec = 5
    
    countdown(sec)
}

 
 
 
/*
run:

Total time: 5 seconds
Time remaining: 4 seconds
Time remaining: 3 seconds
Time remaining: 2 seconds
Time remaining: 1 seconds
Time remaining: 0 seconds
 
*/
