GridLayout on Java

The GridLayout class is a layout manager that lays out a container's components in a rectangular grid. The container is divided into equal-sized rectangles, and one component is placed in each rectangle. For example, the following is an applet that lays out 3 textfields and 3 labels into three rows and two columns:


import javax.swing.*;
import java.awt.*;

public class DemoGridLayout extends JFrame{
    public DemoGridLayout(){
        setTitle("Demo Grid Layout");
       
        JPanel p1 = new JPanel();
        GridLayout f = new GridLayout(3, 2, 5, 5);
        p1.setLayout(f);
       
        JLabel lblFirstName = new JLabel("First Name");
        JLabel lblMiddleName = new JLabel("Middle Name");
        JLabel lblLastName = new JLabel("Last Name");
        JTextField txtFirstName = new JTextField(8);
        JTextField txtMiddleName = new JTextField(1);
        JTextField txtLastName = new JTextField(8);
        p1.add(lblFirstName); p1.add(txtFirstName);
        p1.add(lblMiddleName); p1.add(txtMiddleName);
        p1.add(lblLastName); p1.add(txtLastName);
        add(p1);
    }
   
    public static void main(String[]args) {
        JFrame frame = new DemoGridLayout();
        frame.setVisible(true);
        frame.setSize(200,125);
        frame.setDefaultCloseOperation(2);
        frame.setLocationRelativeTo(null);
    }
}
