BorderLayout Example In Java NetBeans

In this java Code we will see How To Use The BorderLayout LayoutManager In Java NetBeans

Source Code:

package javaapp;

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

public class SwingLayout {

public static void main(String[] args){

JFrame frame = new JFrame("BorderLayout");

JPanel panel1 = new JPanel();

panel1.setLayout(new BorderLayout());

// set the button in the top of the container
panel1.add(new JButton("NORTH"), BorderLayout.NORTH);

// set the button in the right of the container
panel1.add(new JButton("EAST"), BorderLayout.EAST);

// set the button in the middle of the container
panel1.add(new JButton("CENTER"), BorderLayout.CENTER);

// set the button in the top of left container
panel1.add(new JButton("WEST"), BorderLayout.WEST);

// set the button in the bottom of the container
panel1.add(new JButton("SOUTH"), BorderLayout.SOUTH);

// create an instance of borderlayout with gaps
BorderLayout bl = new BorderLayout(50,50);

JPanel panel2 = new JPanel(bl);

panel2.add(new JButton("NORTH"), BorderLayout.NORTH);
panel2.add(new JButton("EAST"), BorderLayout.EAST);
panel2.add(new JButton("CENTER"), BorderLayout.CENTER);
panel2.add(new JButton("WEST"), BorderLayout.WEST);
panel2.add(new JButton("SOUTH"), BorderLayout.SOUTH);

bl.removeLayoutComponent(new JButton("NORTH"));

// return the state of the borderlayout Hgap and Vgap
System.out.println(bl.toString());

// return the borderlayout Hgap and Vgap
System.out.println(bl.getHgap()+" - "+bl.getVgap());

frame.add(panel2);

frame.setSize(400, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo(null);
frame.setVisible(true);

}
}

//OUTPUT:

using the panel1

using the panel2

java.awt.BorderLayout[hgap=50,vgap=50]

50 - 50
