How can interaction with the user interface be implemented in the project?

In Java, interaction with the user interface is usually implemented using GUI frameworks such as Swing, JavaFX, or Android SDK (for mobile applications).

Main steps:

1. Create interface components (buttons, input fields, panels, etc.).
2. Add event handlers (for example, ActionListener for buttons) to respond to user actions.
3. Organize the logic for updating the interface and interacting with data.

Example using Swing:

JButton button = new JButton("Click me");
button.addActionListener(e -> System.out.println("Button clicked"));

JFrame frame = new JFrame("Example");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(button);
frame.pack();
frame.setVisible(true);
