Decreasing for loop in Scala?

Question

First day and first attempt at using Scala - so go easy on me! I\'m trying to rewrite some old Java code I have which is simply a function which takes two numbers and prints

Answer 1

def printInDecreasingOrder(start : Int, end : Int){
  if(start > end ){
     for(i <- start to end by -1){
       println(s"Current value (decreasing from $start to $end) is $i")
     }
   }else{
     println("first num is smaller than second")
   }
}

method call:

printInDecreasingOrder(10, 2)

Result:

Current value (decreasing from 10 to 2) is 10

Current value (decreasing from 10 to 2) is 9

Current value (decreasing from 10 to 2) is 8

Current value (decreasing from 10 to 2) is 7

Current value (decreasing from 10 to 2) is 6

Current value (decreasing from 10 to 2) is 5

Current value (decreasing from 10 to 2) is 4

Current value (decreasing from 10 to 2) is 3

Current value (decreasing from 10 to 2) is 2

printInDecreasingOrder(1, 10)

Result:

first num is smaller than second
