I am writing a application that will take user information such as the name, email, password. To get the user information I am using JTextFields. I would like to have all the components in the center of the screen vertically and horizontally, and also have the components stack on top of each other one after the other like so: Expected Design

Like you would see on a website. Currently I am using a JPanel inside a JFrame, the JPanel has a BoxLayout with a BoxLayout.Y_AXIS. Here is my code:

public class RegisterLayout extends Layout {

    @Override
    public void init() {
        this.setBackground(Utilities.babyBlueish);
        this.setBorder(BorderFactory.createTitledBorder("Register Now!"));
        this.setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
    }

    @Override
    public void addComponents() {
        
        JTextField fName = new JTextField("Enter Your Full Name");
        fName = Utilities.designTextField(fName);
        
        JButton submit = new JButton("Submit");
        submit = Utilities.designButton(submit);
        submit.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent arg0) {
                
            }
            
        });
        
        this.add(fName);
        this.add(submit);
    }

}

Both init() and addComponents() are called when the JPanel is added to the JFrame's content pane. "RegisterLayout extends Layout" and "Layout extends JPanel". Currently with the code I have my program looks like this: Current Design. As you can see the JTextField is off center with the screen horizontally and as a whole it is not centered vertically.

If anyone could help I would appreciate it. If you need further details please let me know.
