In the tutorial, JavaSampleApproach will show how to use Kotlin Array methods min(), minBy(), minWith() to find the smallest element in a Kotlin Array.

I. min() method

Kotlin Array method min() is used to returns the smallest element or null if there are no elements. If any of elements is NaN, it returns NaN.

Method signatures:

//1. 
public fun Array<out Double>.min(): Double?

//2. 
public fun Array<out Float>.min(): Float?

Example:


package com.javasampleapproach.kotlin.array

fun main(args : Array){
    val simpleArray = arrayOf(55.4, 20.0, 99.99, 1.99, 23.0, 34.2, 88.0, 72.1, 61.2, 43.9)
     
    // public fun Array.min(): Double?
    val largestElement = simpleArray.max()
    println(largestElement)
    // ->
    /*
        1.99
    */  
}
