How can we add padding to a JTextField in Java?

A JTextField is a subclass of JTextComponent class and it is one of the most important components that allow the user to input text value in a single-line format. A JTextField class will generate an ActionListener interface when we trying to enter some input inside it. The important methods of a JTextField class are setText(), getText(), setBorder(), setEnabled(), etc. 

We can add padding to a JTextField using the setMargin(Insets s) of JTextComponent class.

Syntax

public void setMargin(Insets m)

Example

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class JTextfieldPaddingTest extends JFrame {
   private JTextField jtf;
   public JTextfieldPaddingTest() {
      jtf = new JTextField("Welcome to Tutorials Point");
      jtf.setMargin(new Insets(10, 10, 10, 10));
      add(jtf, BorderLayout.NORTH);
      setSize(400, 300);
      setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      setLocationRelativeTo(null);
      setVisible(true);
   }
   public static void main(String[] args) {
      new JTextfieldPaddingTest();
   }
}
