Kotlin Array find the Largest Element – max() maxBy() maxWith() methods

https://grokonez.com/kotlin/kotlin-array-find-largest-element-max-maxby-maxwith-methods

In the tutorial, JavaSampleApproach will show how to use Kotlin Array methods max(), maxBy(), maxWith() to find the largest element in a Kotlin Array.

I. max() method

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

Method signatures:

//1. 
public fun Array.max(): Double?

//2. 
public fun Array.max(): Float?

Example:

package com.javasampleapproach.kotlin.array

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

max() with Comparable
