In this program, we are going to share Java program for reversing the linked list with the output. If you are a Java beginner and want to start learning the Java programming, then keep your close attention in this tutorial as I am going to share how to write a java program to for reversing the linked list.
Copy the below Java program and execute it with the help of Javac compiler. At the end of this program, We have shared the output of this program.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 | class LinkedList { static Node head; static class Node { int data; Node next; Node(int d) { data = d; next = null; } } /* Function to reverse the linked list */ Node reverse(Node node) { Node prev = null; Node current = node; Node next = null; while (current != null) { next = current.next; current.next = prev; prev = current; current = next; } node = prev; return node; } // prints content of double linked list void printList(Node node) { while (node != null) { System.out.print(node.data + " "); node = node.next; } } public static void main(String[] args) { LinkedList list = new LinkedList(); list.head = new Node(85); list.head.next = new Node(15); list.head.next.next = new Node(4); list.head.next.next.next = new Node(20); System.out.println("Entered Linked list"); list.printList(head); head = list.reverse(head); System.out.println(""); System.out.println("Reversed linked list "); list.printList(head); } } |
Entered linked list
85 15 4 20
Reversed Linked list
20 4 15 85
