Question

I am trying to align 2 JPanles in a big panel. I am not able to align them properly. I am giving the link to the source code here. If you run the source code, you can see that the New Payment Method Radio Button is at the centre and and not just below the payment options panel. How do i get it there. I am extremely sorry for not able to post the screenshot and also for the long code. THANKS A TON IN ADVANCE.

As an alternative, consider BoxLayout, shown below.

import java.awt.EventQueue;
import javax.swing.Box;
import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JRadioButton;

/** @see http://stackoverflow.com/questions/6911309 */
public class PaymentPanel extends Box {

    public PaymentPanel() {
        super(BoxLayout.Y_AXIS);
        this.add(new JLabel("Payment Setup"));
        this.add(Box.createVerticalStrut(10));
        this.add(new JRadioButton("New payment Method", true));
        this.add(Box.createVerticalStrut(10));
        this.add(new JLabel("Invoice"));
    }

    private void display() {
        JFrame f = new JFrame("PaymentPanel");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.add(this);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                new PaymentPanel().display();
            }
        });
    }
}
