import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JButton;
import javax.swing.JScrollPane;
import javax.swing.ListModel;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class JavaJListExample extends JFrame  implements ActionListener{
    public JList list;
    public JButton button;
    JavaJListExample()
    {
        super("JList");

        String language []={"Java","C++","PHP","Python","C#"};
        list=new JList();
        list.setListData(language);
        list.setVisibleRowCount(3);

        JScrollPane pane=new JScrollPane(list);
        pane.setBounds(50, 50, 100, 50);
        add(pane);

        button=new JButton("Click me");

Java JList.getModel Code Explanation

When the JButton is clicked by the user, Abstract [public void actionPerformed(ActionEvent event)

    {

        ListModel m=list.getModel();
        System.out.println("The ListModel is " +m);

    }]

ActionListener method is performed.We get list model using getModel() method and store it as variable M.

[ JScrollPane pane=new JScrollPane(list);] code adds scroll ability to the JList.

[ setDefaultCloseOperation(EXIT_ON_CLOSE);] exits application when the close button is clicked.

Above class extends JFrame i.e it inherits all JFrame methods like setLayout,setSize etc
