Solution

Components can be added to a container in Swing using the add() method. Here are the steps:

  1. First, create a new instance of the component you want to add. This could be a button, label, text field, etc. For example: JButton button = new JButton("Click me");

  2. Next, create an instance of the container you want to add the component to. This could be a JFrame, JPanel, etc. For example: JPanel panel = new JPanel();

  3. Then, use the add() method on the container to add the component. For example: panel.add(button);

  4. If the container is a JFrame, you need to set its size, set its default close operation, and make it visible. For example:

JFrame frame = new JFrame();
frame.setSize(300, 200);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(panel);
frame.setVisible(true);
  1. If the container is a JPanel and it's already added to a JFrame, you just need to revalidate and repaint the JFrame. For example:
frame.revalidate();
frame.repaint();

Note: The setLayout() method is used to set the layout manager for the container, which determines how the components are laid out. The setVisible() method is used to make the container visible.
