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
Modify the Program Above Using the lambda Function in Java 8 This article defines what a sort comparator in Java is and demonstrates how you can use it in processes. We’ve included programs you can follow to help you understand this concept better. Use the DepartmentComparator to Sort Eleme...
We can use thesort()function from theCollectionsClass to sort a list. We can take the list object, and it modifies the order of the elements. It sorts the list in ascending order. For example, importjava.util.*;importjava.util.stream.*;publicclassMain{publicstaticvoidmain(String[]args){...

We introduced the notion of a Comparator in Java, which is used to specify the sort order of a particular class. Let's start with an example to sort Strings by their length. We thus want to write a Comparator that compares Strings. So the general format of our Comparator will be as ...
So far, we've seen how to sort data that in Javaland is "naturally" sortable, i.e. implements the Comparable interface, or else make our own data implement Comparable so that it can be sorted. But of course this model has limitations: ...
