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 Streamsorted()to Sort a List in Reverse Order in Java We can also provide the order in which the sorting takes place. To get the output or sorted stream in reversed order, specify it inside thesortedmethod by telling the comparator to use the reverse order. ...
In this post, we are going to sort anArrayListin Java.ArrayListis a class that is an implementation of List interface and used to store data. Sorting is one of the fundamental operations of data that we use in day to day programming. To sort an ArrayList there are several ways such as ...

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 ...
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())/...
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.
First, let's see how to sort an array in ascending order in Java using theCollections.sort()method. This method is overloaded, which means you can sort the ArrayList in natural order by leveraging the default comparator, which sorts the list in the natural order, and you can use theCollec...
