![]() Now let us see the syntax of the Collections.sort() Method in java. Basically, it takes the elements of ArrayList as parameters and sorts them in ascending order, and returns an ArrayList that is sorted in ascending order, with respect to the original ordering of its elements. ![]() Using the sort() method of the collections class we can sort ArrayList in ascending order in java. Let's discuss these sorting methods in detail. Mainly the collections class provides two methods to sort an ArrayList in Java in ascending or descending order. An ArrayList can be sorted in two ways ascending or descending order. To arrange the data in a sorted manner we use different methods. Usually, the elements are stored in an unsorted manner. in which multiple elements or objects can be stored. In Java, there is a collection framework that provides interfaces like List, Set, Stack, Queue, etc., and also classes like LinkedList, ArrayList, etc. So here, in this article, we are going to learn how we can sort an ArrayList in java, to arrange the elements in an ArrayList in ascending or descending order. Note: An ArrayList in java can store the elements in an unsorted manner, not in ascending or descending order but just index-wise. ![]() So we can add as many elements as we want inside an ArrayList, but it should not exceed the memory limit the JVM has available. An ArrayList is a dynamic data structure that stores elements in it dynamically, that is it does not have any size limits. It usually inherits the properties of the AbstractList class. Before getting started with the topic of sorting ArrayList in java, let us get a short overview of what is an ArrayList in java.Īrraylist in java : An ArrayList** in java is a Collections framework class which exists inside the java.util package. In this article, we are going to learn about how to sort ArrayList in java. ![]()
