Example Java Program for JFrame card Layout (GUI)

This java code uses grid bag layout to arrange the button components.

// importing swing package for JFrame, JButton controls
import javax.swing.*;
// importing to use Container class
import java.awt.*;

public class GridBagLayoutTest extends JFrame {
	public GridBagLayoutTest(){
		// Setting Title to the JFrame GUI
		setTitle("Grid Bag Layout Test Java Code");
		// Setting grid bag layout to JFrame GUI
		setLayout(new GridBagLayout());
		
		// Setting position for the component
		GridBagConstraints place = new GridBagConstraints();
		place.gridx = 5;
		place.gridy = 0;
		
		// Adding buttons using Grid Bag Layout
		add(new JButton("Button1"), place);
		
		//Setting position for the button2 component
		place.gridx = 0;
		place.gridy = 5;
		
		add(new JButton("Button2"), place);
		
		
		//Setting position for the button2 component
		place.gridx = 2;
		place.gridy = 4;
		
		add(new JButton("Button3"), place);


	}
	public static void main(String[] args){
		// Create JFrame for GUI frame and title as 'Add Button in JFrame Java Code'
		GridBagLayoutTest frame = new GridBagLayoutTest();
		frame.setSize(500,200);
		frame.setVisible(true);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}
}

Once executing this java program, Frame with grid bag layout buttons will be popped up as above and closes if we click close button in the frame title.
