Java - Spring Cleaning with the `clear()` 🧼🧹

Hello Dev.to enthusiasts! 🌟

Ever felt your data structures getting ... messy? 🤔 Just like our rooms need a sprucing up now and then, sometimes our linked lists yearn for a reset. Introducing the clear() method, the ultimate decluttering tool for our singly linked list.

🏛 A Quick Architectural Peek: Our Singly Linked List

For the coding novices and the forgetful alike, here's a recap:

class Node { int data; Node next; Node(int data) { this.data = data; this.next = null; } } class SinglyLinkedList { Node head; SinglyLinkedList() { this.head = null; } } 

Picture each node as a book 📚 on a vast bookshelf. Over time, these books accumulate, sometimes needing a rearrangement or cleanup.

🧙‍♂️ The Magic of clear()

public void clear() { // It's like magically making every book disappear for a fresh start. head = null; } 

🤷‍♀️ Why clear()?

One word: Efficiency ⚙️. Instead of tediously removing each node (or book), clear() offers a fresh slate in one quick step. It's the reboot button 🔄 we sometimes need for our code.

In the next article we will look at insertAt(index, data) method

Cheers and happy coding! 🚀
