How to create a GridLayout with rows and columns in Java?

While creating a GridLayout, you need to set the rows and columns as parenthesis. A GridLayout is used to create a layout the specified number of rows and columns.

Let’s say we have a GridLayout, with 1 row and 4 columns −

GridLayout layout = new GridLayout(1,4);

The following is an example to create a GridLayout with rows and columns −

Example

package my;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextArea;
import javax.swing.WindowConstants;
public class SwingDemo {
   public static void main(String[] args) {
      JFrame frame = new JFrame("Sections");
      JPanel panel = new JPanel();
      panel.setBackground(Color.orange);
      GridLayout layout = new GridLayout(1,4);
      layout.setHgap(40);
      panel.setLayout(layout);
      panel.add(new JButton("Overview"));
      panel.add(new JButton("Samples"));
      panel.add(new JButton("Tutorials"));
      panel.add(new JButton("Support"));
      frame.add(panel);
      frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
      frame.setSize(500, 300);
      frame.setVisible(true);
   }
}
