Overview

In this tutorial, we will learn about Java Swing BorderLayout with an example demo program. A border layout lays out a container, arranging and resizing its components to fit in five regions:

• NORTH
• SOUTH
• EAST
• WEST
• CENTER

BorderLayout also supports relative positioning in the container:

• PAGE_START
• PAGE_END
• LINE_START
• CENTER
• LINE_END

Java Demo Program

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import java.awt.*;

//BorderLayout Demo Program
public class BorderLayoutDemo {
    public static void main(String[] args) {

        JFrame frame = new JFrame("BorderLayout - www.TestingDocs.com");
        JButton btn1 = new JButton("Button [NORTH]");
        JButton btn2 = new JButton("Button [CENTER]");
        JButton btn3 = new JButton("Button [WEST]");
        JButton btn4 = new JButton("Button [SOUTH]");
        JButton btn5 = new JButton("Button [EAST]");

        JPanel panel = new JPanel(new BorderLayout());
        panel.add(btn1, BorderLayout.NORTH);
        panel.add(btn2, BorderLayout.CENTER);
        panel.add(btn3, BorderLayout.WEST);
        panel.add(btn4, BorderLayout.SOUTH);
        panel.add(btn5, BorderLayout.EAST);
       

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(600,300);
        frame.getContentPane().add(panel);
        frame.setVisible(true);
    }
}

Output

Run the Java application to view the output.

 

We can use the constants of the BorderLayout class to indicate the area we want to place a component in the container.
