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.

Cheers and happy coding! 🚀
