If you are working on Java 8 or higher version then you can take advantage of stream API to sort an ArrayList. Here, we are using the sorted() method of the stream that helps to sort stream elements. import java.util.ArrayList; import java.util.stream.Collectors; public class Main { pu...
In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Jav...
Use the DepartmentComparator to Sort Elements in Java Sorting is the process of arranging the data structures like a list array in a definite sequential order. The process works by comparing the data elements, hence, defining the new positions. There are various types of sort algorithms defined ...
In this article, we will learn to sort elements of Java Map. It is very much required to sort them based on the values to make decisions based on values.
In Java 8 – How to sort a Map? On Crunchify we have written almost ~400 java tutorials and this one is an addition to Java8 category. I love Java
The sort( ) method sorts the array elements in place and returns the sorted array. By default, the sort order is ascending, built upon converting the elements into strings and then comparing their sequences of UTF-16 code unit values. Number sorting can be incorrect as the sort( ) method...
In this tutorial, first, we will compare two array lists using a comparison method in Java. We also apply the same method on Java strings before applying it on array lists. Finally, we demonstrate, how you can sort an unordered array list before comparis

First, let’s see how to solve the problem if our Java is older than Java 8. LinkedHashMap’s entrySet()provides access to all entries while maintaining their original order. We can also leverage theCollections.sort()method, which allows us to sort a collection of objects by a givenCompar...
Java programs to sort a stream of strings usingStream.sorted()method in ascending and descending order. Sort stream of strings Stream<String>wordStream=Stream.of("A","C","E","B","D");wordStream.sorted()//ascending.forEach(System.out::println);wordStream.sorted(Comparator.reverseOrder())/...
