Thread: Combine Prime Factor Code into JPanel

I have a working JFrame GUI with my JPanel all setup. I am trying to combine two different codes that I've got setup and working. The first code was a text converter toUpperCase in a JPanel, and the second is a Prime Factor (not prime numbers) code. I've been trying to get the JPanel to give an output of Prime Factors for any number that a user inputs. Here is what I have....

public class Prime extends JPanel { 
    private JLabel formattedText;
 
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.getContentPane().add(new Prime());
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        frame.setVisible(true);
    }
 
    public Prime(){
        setLayout(new BoxLayout(this,BoxLayout.Y_AXIS));
        JPanel panel = new JPanel(); panel.setPreferredSize(new Dimension(640,100));
        JLabel label = new JLabel("Enter a number to check for it's prime number(s).");
        JTextField field = new JTextField("0");
        field.addActionListener(new FieldListener());
        add(label);
        add(field);
        add(panel);
 
 
        panel = new JPanel(); panel.setPreferredSize(new Dimension(640,380));
        formattedText = new JLabel();
        panel.add(formattedText);
        add(panel);
    }
 
    private class FieldListener implements ActionListener {
        public void actionPerformed(ActionEvent event) {
            JTextField field = (JTextField)event.getSource();
                formattedText.setText(field.getText().toUpperCase()); // I know this is wrong... I can't figure out what to change here to get it to pull the code below.
            }
    }
    public class PrimeFactors {
 
    }
}

and here is the Prime Factor code

public class Temp {
 
    static int primeCheck = 1;
 
    public static void main(String[] args) {
        System.out.println("Enter a number whose Prime factors are desired: ");
        Scanner numS = new Scanner(System.in);
        int numPriFac = 0;
        if (numS.hasNextInt()) {
            numPriFac = numS.nextInt();
        }
 
        System.out.println("All the Prime Factors of the entered number are:");
 
        for (int tap = 1; tap <= numPriFac; tap++) {
            if (numPriFac % tap == 0) {
                for (int primeTest = 2; primeTest < tap; primeTest++) {
                    if (tap % primeTest == 0) {
                        primeCheck = 1;
                        break;
                    } else {
                        primeCheck = 0;
                    }
                }
                if (primeCheck == 0 || tap == 2) {
                    System.out.print(tap + " ");
                }
            }
        }
    }
}

That last PrimeFactors code in the bottom is just something left over from when I was trying to get it working on my own. Thanks so much for any help!!!

The code for the GUI works and the code for the JPanel works, but I jwant to combine the two codes so that I can have a GUI for the user to input a number to have it's Prime Factors returned.
