 import java.time.LocalDateTime
 import java.time.format.DateTimeFormatter

// Create a convert function, String -> LocalDateTime
val dateTimeStrToLocalDateTime: (String) -> LocalDateTime = {
    LocalDateTime.parse(it, DateTimeFormatter.ofPattern("dd-MM-yyyy | HH:mm"))
}

val list = listOf("14-10-2016 | 15:48",
        "01-08-2015 | 09:29",
        "15-11-2016 | 19:43")

// You will get List<LocalDateTime> sorted in ascending order
list.map(dateTimeStrToLocalDateTime).sorted()

// You will get List<LocalDateTime> sorted in descending order
list.map(dateTimeStrToLocalDateTime).sortedDescending()

// You will get List<String> which is sorted in ascending order
list.sortedBy(dateTimeStrToLocalDateTime)

// You will get List<String> which is sorted in descending order
list.sortedByDescending(dateTimeStrToLocalDateTime)
