Exercise Evaluations
Exercise 1: Example of JFrame (1.5/1.5)
The implementation meets all requirements, including creating a JFrame with a title, minimum size, and a centered label. The use of BorderLayout and the explanation of ContentPane were insightful. The post provides clear step-by-step instructions and an output demonstration.
Exercise 2: Discovering New Components (1.5/1.5)
The task was executed correctly by creating a JFrame with a button, a text field, and a text area. Customizations such as tooltips, colors, and a non-editable text field with a border were well implemented. The visual output and the detailed explanations support the implementation.
Exercise 3: Associating Actions with Buttons (1.5/1.5)
The use of ActionListener to handle button actions was demonstrated effectively. The dynamic creation of buttons and updating the frame’s title shows scalability. The step-by-step explanation and visual output were detailed and easy to follow.
Exercise 3bis: AbstractAction (1.5/1.5)
Refactoring the solution using AbstractAction was implemented correctly, showcasing a better design pattern. The approach to encapsulate actions and reuse them across buttons demonstrates an advanced understanding of Swing programming. The output was well-demonstrated.
Exercise 4: Event Listeners (2/2)
The program to dynamically add and remove buttons was implemented flawlessly. The inclusion of the "Add" and "Reset" buttons, with proper event handling, enhances the user experience. The use of FlowLayout and the dynamic update of the panel were handled well.
Exercise 5: Factorial (2/2)
The factorial calculator program meets the task requirements, including input validation and edge case handling for numbers ≥ 17. The use of JOptionPane for error messages and the dynamic updates to the label and button text were well-executed.
Exercise 6: What is Your Age? (2/2)
The GUI layout with editable and non-editable text fields was implemented effectively. The separation of interface design and event handling into different packages demonstrates modular programming. The age calculation and reverse functionality work correctly, and the output is visually appealing.
Exercise 7: JTable Component (2/2)
The implementation of the JTable component, including sorting by favorite language and color-coding rows, was outstanding. The use of AbstractTableModel and DefaultTableCellRenderer highlights advanced Swing programming skills. The Singleton pattern in the LanguageService class was a nice touch, and the visual output is clear and well-structured.
Comments and Recommendations
Your post is a comprehensive exploration of Swing programming. The detailed explanations, well-structured code, and visual demonstrations make it easy to follow and educational. The use of advanced concepts like AbstractAction, custom cell renderers, and modular programming demonstrates your strong command of the topic. Great job!
