To do list using java

[Dev-Aditya-More]

This pull request adds a simple console-based To-Do List application written in Java.
The application allows users to:

* Add tasks to a list
* Remove tasks by their index
* View all tasks in the current list
* Exit the application via a user-friendly menu

Key Features:

* Task Class: Encapsulates the task's description as an object.
* ArrayList Management: Uses an ArrayList to dynamically manage the tasks.
* Console Menu: Provides an interactive user interface for adding, removing, and viewing tasks.
* Input Validation: Ensures users don't remove tasks that don't exist and handles invalid input gracefully.
