+Task Manager GUI
+The Task Manager GUI is a Java application designed to help users manage their tasks effectively. It provides a graphical user interface (GUI) for adding, viewing, and deleting tasks, along with displaying task details such as title, description, and deadline.
+
+Features
+Add Task: Users can add new tasks by providing a title, description, and deadline in the specified format (dd/MM/yyyy HH:mm).
+View Tasks: Users can view all added tasks sorted by their deadlines.The task which is to be done first is displayed first based on the deadline. Tasks are displayed in a text area within the GUI.
+Delete Task: Users can select and delete tasks from the list. Tasks are deleted based on their titles.
+
+
+Tools andTechniques used
+ArrayList: Used to store the tasks added by the user. The ArrayList allows for dynamic resizing and efficient storage and retrieval of task objects.
+Date: Utilized to represent task deadlines. Dates are parsed and formatted using the SimpleDateFormat class, ensuring consistency and compatibility with user input and display.
+JTextArea: Used to display tasks within the GUI. The JTextArea component provides a scrollable text area for presenting task details to the user.
+JScrollPane: Incorporated to enable scrolling functionality within the JTextArea when the number of tasks exceeds the visible area, ensuring a seamless user experience.
+Custom Comparator: Implemented a custom comparator (TaskComparator) to sort tasks based on their deadlines. This comparator is used in conjunction with Collections.sort() to maintain tasks in ascending order of deadlines.
+
+
+Requirements
+Java Development Kit (JDK) 
+Java Swing library for GUI components
