![]() ![]() We can sort the LinkedList by use of the Collections.sort(Comparator c) method. There is another method provided by the Collections class. Name of Student = kamboj Collections.sort(Comparator c) ListOfStudent.sort(new RollNoComparator()) It Sorts all the objects based on RollNo ListOfStudent.add(new Student(3,"kamboj",20)) ListOfStudent.add(new Student(2,"kant",27)) ListOfStudent.add(new Student(1,"Ravi",26)) LinkedList listOfStudent = new LinkedList() import Ĭlass AgeComparator implements int compare(Student student1, Student student2)Ĭlass RollNoComparator implements int compare(Student student1, Student student2) Let’s see linked list sorting by linked list program in java. and we want to sort the LinkedListon based on different criteria. Suppose we have a LinkedList that containing the object of User-defined class that is Student. Public int compare(String string1, String string2)Īfter sorting: Sorting of LinkedList contains User-defined class objects ![]() LinkedList listOfNames = new LinkedList() Void, This method doesn’t return anything because it’s return type is void.Ĭ, Object of comparator import Let’s see the linked list sorting public void sort(Comparator c) We can sort the LinkedList by sort(Comparator c) method that will sort the Strings alphabetically in ascending order. Suppose we have a LinkedList with some string objects and objects are not in sorted order. If you are not familiar with the Comparator interface then read the Comparator interface first. Let’s take an example of LinkedList and sort the objects of LinkedList. The sort() method is defined in the List interface and it is a default method. Collections.sort(Comparator c) LinkedList.sort(Comparator c) Here is the table content of the article will we will cover this topic.Ģ. In this post, we will see the sorting of LinkedList objects that totally depends on Comparable or Comparator. But there may be a situation when we want to perform some complex on LinkedList like how to sort a linked list. In java, we have how to perform some basic operations on Java LinkedList.
