Java program for reversing a linked list using in-built collections class Let us look at the below example for a better understanding of the above algorithm. Print the linked list elements after reversing.Use the In-built Collections.reverse() method for reversing a linked list.Print the linked list elements before reversing.Append the elements at the end of the list.Use the add method to add the elements.Declare a linked list of integer types without any initial size.In this program, we will see how to reverse a linked list in java using the collections class. Program 1: Java Program to Reverse a Linked List Let us look at each of these approaches for a better understanding. This can be done by using the following methods:Īpproach 2: Without Using an In-built Method Output: Before Reversing the Linked List: 6 7 8 9 5Īfter Reversing the Linked List: 5 9 8 7 6 Input: Enter the Linked List elements: 6 7 8 4 5 But before moving further, if you are not familiar with the concept of the linked list in java, then do check the article on Linked List in Java. Due to the dynamicity and ease of insertions and deletions, they are preferred over the arrays. LinkedList is a linear data structure where the elements are not stored in contiguous locations and every element is a separate object with a data part and address part. In this tutorial, we will see how to reverse a linked list in java. Check Whether a Character is Alphabet or Not.Check Whether a Number is Positive or Negative.Accept Array Elements and Calculate the Sum.Count the Number of Occurrence of an Element.Cyclically Permute the Elements of an Array.Delete the Specified Integer From an Array.
Insert an Element at Specified Position.Put Even and Odd Elements in Two Separate Arrays.
