Mastering Singly Linked List Logical Operations in Java

Singly linked lists are versatile data structures that offer efficient insertion, deletion, and traversal operations. However, beyond the basic CRUD (Create, Read, Update, Delete) operations, there lies a realm of logical operations that can be performed on singly linked lists. In this detailed blog, we’ll explore some of the most important logical operations that can be applied to singly linked lists in Java, providing insights into their implementation and usage.

How to search an element in a LinkedList in java?

head → 10 → 8 → 1 → 11 → null

ListNode current = head;
while(current != null)
{
  if(current.data == searchKey)
  {
    return true;
  }
  current = current.next;
}
return false;

As the main logic, we need to traverse the list node by node. While traversing, we check each node’s data. If it matches the search key, then we’ve found the key; otherwise, we haven’t found it.

1. We create a temporary node current to traverse the list until the end. Initially, it's set to the head node, i.e., ListNode current = head.
2. Using a while loop, we traverse until the end of the list. If current becomes null, it means we've reached the end, and we terminate the loop. During traversal, we check each…
