    Default Merge java files into one and how to use keylistener or key bindings?

    I have two questions. A. How do I merge my two .java files and B. how do I use keylistener or keybindings in my code ? I am open to either keylisteners or keybindings and have tried to do this, but I have not been sucessful.
    I am using two files, which compile fine and run exactly as I have them coded. I am very new to Java, but have worked with HTML and Autohotkey extensivly, Autohotkey more than HTML. Any help would be appreciated.
    RiskApp.java:
    import javax.swing.*;
    import java.text.NumberFormat;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import javax.swing.SwingUtilities;
    import java.awt.*;
    import java.awt.event.*;
     
    public class RiskApp extends JFrame {
        private static void createAndShowGUI() {
            JFrame frame = new JFrame("Risk");
    JPanel panel = new JPanel(new BorderLayout());
    Container contentPane = frame.getContentPane();
    contentPane.setLayout(new GridLayout(1,2));
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            Risk riskPanel = new Risk();
            frame.getContentPane().add(riskPanel);
            frame.setSize(305,90);
            frame.setResizable(false);
            frame.setVisible(true);
        }
     
        public static void main(String[] args) {
            javax.swing.SwingUtilities.invokeLater(new Runnable() {
                public void run() {
    try {
    UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
    } catch (UnsupportedLookAndFeelException e) {
    } catch (ClassNotFoundException e) {
    } catch (InstantiationException e) {
    } catch (IllegalAccessException e) {
    }
                    createAndShowGUI();
                }
            });
        }
