Java Program for Grid Layout GUI

Java Program for JFrame Grid Layout(GUI)

In java programming, we can also use grid layout in JFrame to create a Graphical user interface (GUI) using JFrame class.

In Java JFrame, need to set the layout to add the components.

Grid Layout is used to put the components with an arrangement of rows and columns in the JFrame.

How to add grid layout in Java ?

setLayout(new GridLayout(int rows, int columns));

Example Java Program for JFrame Grid Layout (GUI)

This java code uses 2 rows and 4 columns in grid layout to arrange the 8 button components.

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

public class GridLayoutTest extends JFrame {
	public GridLayoutTest(){
		// Setting Title to the JFrame GUI
		setTitle("Grid Layout Test Java Code");
		// Setting grid  layout to JFrame GUI
		setLayout(new GridLayout(2,4));
		// Adding buttons using Grid Layout
		add(new JButton("Button1"));
		add(new JButton("Button2"));
		add(new JButton("Button3"));
		add(new JButton("Button4"));
		add(new JButton("Button5"));
		add(new JButton("Button6"));
		add(new JButton("Button7"));
		add(new JButton("Button8"));
	}
	public static void main(String[] args){
		// Create JFrame for GUI frame and title as 'Add Button in JFrame Java Code'
		GridLayoutTest frame = new GridLayoutTest();
		frame.setSize(500,200);
		frame.setVisible(true);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}
}

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

		// Setting grid  layout to JFrame GUI
		setLayout(new GridLayout(2,4));
		// Adding buttons using Grid Layout
		add(new JButton("Button1"));
		add(new JButton("Button2"));
		add(new JButton("Button3"));
		add(new JButton("Button4"));
		add(new JButton("Button5"));
		add(new JButton("Button6"));
		add(new JButton("Button7"));

		setLayout(new GridLayout(2,4));
		// Adding buttons using Grid Layout
		add(new JButton("Button1"));
		add(new JButton("Button2"));
		add(new JButton("Button3"));
		add(new JButton("Button4"));
		add(new JButton("Button5"));
		add(new JButton("Button6"));
