السلام عليكم اريد شرح كود برمجي كيفية عمله public class TaskNode { int taskId; String taskDescription; String deadline; TaskNode next; // Constructor public TaskNode(int taskId, String taskDescription, String deadline) { this.taskId = taskId; this.taskDescription = taskDescription; this.deadline = deadline; this.next = this; // Initially points to itself } } public class CircularLinkedList { private TaskNode head = null; } // Method to insert a task at the beginning of the list public void insertAtBeginning(int taskId, String taskDescription, String deadline) { TaskNode newNode = new TaskNode(taskId, taskDescription, deadline); if (head == null) { head = newNode; } else { TaskNode temp = head; while (temp.next != head) { temp = temp.next; } temp.next = newNode; newNode.next = head; } head = newNode; } // Method to remove a task from the beginning of the list public void removeFromBeginning() { if (head == null) { System.out.println("List is empty."); return; } if (head.next == head) { head = null; // Only one node in the list } else { TaskNode last = head; while (last.next != head) { last = last.next; } last.next = head.next; head = head.next; } } // Method to display the list public void display() { if (head == null) { System.out.println("List is empty."); return; } TaskNode temp = head; do { System.out.println("Task ID: " + temp.taskId + ", Description: " + temp.taskDescription + ", Deadline: " + temp.deadline); temp = temp.next; } while (temp != head); } public class Main { public static void main(String[] args) { CircularLinkedList todoList = new CircularLinkedList(); todoList.insertAtBeginning(1, "Complete Java assignment", "2024-03-10"); todoList.insertAtBeginning(2, "Prepare for the meeting", "2024-03-05"); todoList.display(); todoList.removeFromBeginning(); todoList.display();     } }
