How to do it…

We will now see how to sort in descending order using some examples:

1. First, we will try to sort a simple list of integers:

val listOfInt= listOf(1,2,3,4,5)var sortedList=listOfInt.sortedDescending()sortedList.forEach {    print("${it} ")}

This is the output:

5 4 3 2 1

2. Now, let's use our list of Person from the preceding recipe. To sort it in descending order, this is what we will do:

val p1=Person(91)val p2=Person(10)val p3=Person(78)val listOfPerson= listOf<Person>(p1,p2,p3)val sortedListOfPerson=listOfPerson.sortedByDescending {    it.age}sortedListOfPerson.forEach {    print("${it.age} ")}

Here's the output:

91 78 10
