Hello Dev.to enthusiasts! π
Ever felt your data structures getting ... messy? π€ 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.
π 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 π on a vast bookshelf. Over time, these books accumulate, sometimes needing a rearrangement or cleanup.
π§ββοΈ The Magic of clear()
public void clear() {
// It's like magically making every book disappear for a fresh start.
head = null;
}
π€·ββοΈ Why clear()
?
One word: Efficiency βοΈ. Instead of tediously removing each node (or book), clear()
offers a fresh slate in one quick step. It's the reboot button π we sometimes need for our code.
In the next article
we will look at insertAt(index, data)
method
Cheers and happy coding! π
