scala order list

To order a list in Scala, you can use the sorted method. This method sorts the elements of a collection in ascending order. Here's an example:

val myList = List(5, 3, 1, 4, 2)
val orderedList = myList.sorted

In this example, we have a list called myList with elements [5, 3, 1, 4, 2]. We call the sorted method on myList, which returns a new list orderedList with elements [1, 2, 3, 4, 5]. The original list myList remains unchanged.

If you want to sort the list in descending order, you can use the reverse method after calling sorted:

val descendingList = myList.sorted.reverse

In this case, descendingList will have elements [5, 4, 3, 2, 1].

You can also provide a custom ordering function to the sorted method if you want to sort the list based on a specific criterion. For example, if you have a list of strings and you want to sort them based on their lengths, you can do the following:

val stringList = List("apple", "banana", "cat", "dog")
val orderedStringList = stringList.sorted(

The function specifies that the elements should be sorted based on their lengths. In this case, orderedStringList will have elements List("cat", "dog", "apple", "banana"), as the strings are sorted in ascending order based on their lengths.

These are some ways you can order a list in Scala using the sorted method.
