    <p>I am creating a program where the user selects an item from a list, then the user enters a text to a TextField and then they press a button which then alerts the user of which item was selected alongside the text from the user.how do I go about alerting the user of which item was selected alongside the text from the user when the button is clicked.</p> <pre><code>import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class fruitList extends JFrame implements ListSelectionListener { private JTextField textField; private JList&lt;String&gt; fruitList; private JButton buttonwhich; private static fruitList frame; public static void main(String[] args) { fruitList frame = new fruitList(); frame.setTitle("Fruit List"); frame.setSize(350,150); frame.setVisible(true); frame.setDefaultCloseOperation(EXIT_ON_CLOSE); } public fruitList() { final String[] FRUIT_NAME = {"Banana", "Apple", "Orange"}; setLayout(new FlowLayout()); buttonwhich = new JButton("Which"); fruitList = new JList&lt;String&gt;(FRUIT_NAME); fruitList.setVisibleRowCount(2); add(new JScrollPane(fruitList)); fruitList.addListSelectionListener(this); textField = new JTextField(10); add(textField); add(buttonwhich); ButtonHandler handler = new ButtonHandler(); buttonwhich.addActionListener(handler); } class ButtonHandler implements ActionListener { public void actionPerformed(ActionEvent e) { JOptionPane.showMessageDialog(frame, "You Pressed \t" + e.getActionCommand()); } } } </code></pre>

    2. COAnd that is what I am not understanding the ListSelectionListener and the ActionListener are giving me errors when put in the same program.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
