Kotlin Program:

Example:

import java.util.Scanner
fun main(args: Array<String>) {
  
  print("Enter two numbers : ");
  val userInput = Scanner(System.`in`)
  var n1:Int = userInput.nextInt()
  var n2:Int = userInput.nextInt()
  
  if(n1>n2) print(n1)
  else print(n2)

  print("is the largest number")
}

Output:

  Enter two numbers : 7
  5
  7 is the largest number

Here, we use 2 variables (above code n1 & n2) to take numbers from the user

Now, check for the largest number using if statement

if(n1>n2){
  // if true print n1
}
else {
  // if false print n2
}

OR

if(n1<n2){
  // if true print n2
}
else {
  // if false print n1
}
