将JButton添加到JTextArea

Question

How can I add JButton on JTextArea ? I have such a code, when I print name of country in JTextField some information using REST displays on JTextArea . But I want to use for this purpose JButton. When user click JButton information will be start searching and then display.

public class Client extends JPanel implements ActionListener{

protected JTextField textField;
protected JTextArea textArea;
protected static JButton search;

public Client() {
    super(new GridBagLayout());

    search = new JButton("Search");
    search.setBounds(100,190,60,30);

    textField = new JTextField(20);
    textField.addActionListener(this);

    textArea = new JTextArea(10, 20);
    textArea.setEditable(false);
    JScrollPane scrollPane = new JScrollPane(textArea);

    GridBagConstraints c = new GridBagConstraints();
    c.gridwidth = GridBagConstraints.REMAINDER;

    c.fill = GridBagConstraints.HORIZONTAL;
    add(textField, c);

    c.fill = GridBagConstraints.BOTH;
    c.weightx = 1.0;
    c.weighty = 1.0;
    add(scrollPane, c);
}

My program show such a window, I want to place my button on the bottom of the window (on the picture).

I don't know what are you expecting exactly, but I wrote this code, I'm not use your code, cause I can't run it, but I think this is that you want.

JFrame gui = new JFrame("Button on bottom.");

JPanel panel = new JPanel(new BorderLayout());

JTextField textfield = new JTextField();
textfield.setText("Australia");

JTextArea textarea = new JTextArea();
textarea.setText("Australia, -27, 133. AUD");

JButton button = new JButton("Button on bottom.");
button.setFont(new java.awt.Font("Dialog", 0, 15));
button.setBorderPainted(false);
button.setFocusable(false);
button.setForeground(new java.awt.Color(255, 255, 255));
button.setBackground(new java.awt.Color(0, 140, 255));

panel.add(textfield, BorderLayout.PAGE_START);
panel.add(textarea);
panel.add(button, BorderLayout.PAGE_END);

gui.setDefaultCloseOperation(gui.EXIT_ON_CLOSE);
gui.setSize(300, 300);
gui.setLocationRelativeTo(null);
gui.add(panel);
gui.setVisible(true);}}
