Kotlin Program to Sort ArrayList of Custom Objects By PropertyIn this program, you'll learn to sort an arraylist of custom object by their given property in Kotlin. Show Example: Sort ArrayList of Custom Objects By Propertyimport java.util.* fun main(args: Array<String>) { val list = ArrayList<CustomObject>() list.add(CustomObject("Z")) list.add(CustomObject("A")) list.add(CustomObject("B")) list.add(CustomObject("X")) list.add(CustomObject("Aa")) var sortedList = list.sortedWith(compareBy({ it.customProperty })) for (obj in sortedList) { println(obj.customProperty) } } public class CustomObject(val customProperty: String) { }When you run the program, the output will be: A Aa B X ZIn the above program, we've defined a CustomObject class with a String property, customProperty. In the main() method, we've created an array list of custom objects list, initialized with 5 objects. For sorting the list with the property, we use list's sortedWith() method. The sortedWith() method takes a comparator compareBy that compares customProperty of each object and sorts it. The sorted list is then stored in the variable sortedList. Here's the equivalent Java code: Java program to sort an ArrayList of custom objects by property. |
