import javax.swing.*;

 

public class BorderLayoutExample {

    public static void main(String[] args) {

        JFrame frame = new JFrame("BorderLayout Example");

        frame.setLayout(new BorderLayout());

 

        JButton btnNorth = new JButton("North");

        JButton btnSouth = new JButton("South");

        JButton btnEast = new JButton("East");

        JButton btnWest = new JButton("West");

        JButton btnCenter = new JButton("Center");

 

        frame.add(btnNorth, BorderLayout.NORTH);

        frame.add(btnSouth, BorderLayout.SOUTH);

        frame.add(btnEast, BorderLayout.EAST);

        frame.add(btnWest, BorderLayout.WEST);

        frame.add(btnCenter, BorderLayout.CENTER);

 

        frame.setSize(300, 200);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.setVisible(true);

    }

}

If you only need to center horizontally, the text-center class is enough; if you need to center vertically or multiple elements, Flexbox or Grid is more suitable. Flexbox is less compatible and may increase complexity, while Grid is more powerful and has a higher learning cost.
