Question
Develop a Java program that creates a simple GUI application for a To-DoList. The program should allow users to add tasks to the list, mark tasks ascompleted, and remove tasks from the list.
Solution
Sure, here is a simple Java program using Swing for GUI that creates a To-Do List application. This program allows users to add tasks, mark tasks as completed, and remove tasks.
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class ToDoList {
private DefaultListModel<String> listModel;
private JList<String> list;
private JTextField textField;
public ToDoList() {
JFrame frame = new JFrame("To-Do List");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 400);
listModel = new DefaultListModel<>();
list = new JList<>(listModel);
JScrollPane scrollPane = new JScrollPane(list);
JPanel panel = new JPanel();
panel.setLayout(new BorderLayout());
textField = new JTextField();
JButton addButton = new JButton("Add Task");
addButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
listModel.addElement(textField.getText());
textField.setText("");
}
});
JButton removeButton = new JButton("Remove Task");
removeButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
listModel.removeElement(list.getSelectedValue());
}
});
panel.add(textField, BorderLayout.CENTER);
panel.add(addButton, BorderLayout.EAST);
panel.add(removeButton, BorderLayout.WEST);
frame.getContentPane().add(scrollPane, BorderLayout.CENTER);
frame.getContentPane().add(panel, BorderLayout.SOUTH);
frame.setVisible(true);
}
public static void main(String[] args) {
new ToDoList();
}
}
This program creates a simple GUI with a text field for entering tasks, an "Add Task" button for adding tasks to the list, and a "Remove Task" button for removing selected tasks from the list. The tasks are displayed in a scrollable list.

Programming AssignmentThis assignment will assess your skills and knowledge to create interactive GUI applications that employ event handling mechanisms.Context: You have been assigned to develop a GUI application for a Student Management System. The application should provide a user-friendly interface for administrators to interact with student records, course enrollment, and grades. The GUI should be implemented using Java's GUI frameworks such as Swing or JavaFX. Event handling mechanisms should be employed to respond to user interactions, and the interface should update dynamically to reflect changes in student records.Requirements:GUI Design:Design an intuitive and user-friendly GUI interface for the Student Management System.Implement the GUI using Java's GUI frameworks such as Swing or JavaFX.Include appropriate components such as labels, text fields, buttons, tables, and menus to display and interact with student records, course enrollment, and grades.Ensure that the GUI is aesthetically pleasing, easy to navigate, and logically organized.Student Management Functionality:Provide functionality to add new students, update student information, and view student details through the GUI interface.Implement event handlers for relevant GUI components, such as buttons or menu items, to perform the corresponding actions.When the "Add Student" button/menu item is clicked, display a form to enter the student's information and add the new student to the system.When the "Update Student" button/menu item is clicked, display a form to select a student and update their information.When the "View Student Details" button/menu item is clicked, display a table or another suitable component to show a list of students and their details.Course Enrollment Functionality:Include functionality to enroll students in courses through the GUI interface.Implement event handlers to respond to actions such as selecting a course and enrolling a student.When a course is selected from a dropdown menu or list, display a list of students eligible for enrollment.Allow administrators to select a student from the list and enroll them in the chosen course.Grade Management Functionality:Incorporate functionality to assign grades to students through the GUI interface.Implement event handlers to respond to actions such as selecting a student, selecting a course, and assigning a grade.When a student is selected from a dropdown menu or list, display a list of courses they are enrolled in and their current grades.Allow administrators to select a course and assign a grade to the selected student.Dynamic Interface Updates:Ensure that the GUI interface updates dynamically to reflect changes in student records, course enrollment, and grades.When a new student is added or information is updated, update the student list or details display accordingly.When a student is enrolled in a course or a grade is assigned, update the corresponding displays to reflect the changes.Error Handling:Implement appropriate error handling mechanisms in the GUI application.Display error messages or dialog boxes when invalid inputs are provided or when operations cannot be completed.Handle exceptions gracefully to ensure the application remains responsive and user-friendly.Documentation:Provide comprehensive documentation for the project, explaining the purpose and usage of each GUI component, event handler, and functionality.Describe the design choices made for the GUI interface and the rationale behind them.Include instructions for running the program and interacting with the GUI interface.
