Create JTextField with border

In this tutorial we are going to see how to create a JTextField with border. This is a very simple way to make your component a little bit more interesting.

In short, in order to create a new JTextField with border, one should follow these steps:

  • Create a class that extends JFrame.
  • Create a new JTextField.
  • Use BorderFactory.createLineBorder(Color.BLUE, 5) to create a new Border.
  • Use setBorder method to set the Border to the text field.
  • Use add to add the field to the frame.

Let’s see the code:

package com.javacodegeeks.snippets.desktop;

import java.awt.Color;
import java.awt.FlowLayout;

import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.border.Border;

public class CreateJTextFieldWithBorder extends JFrame {

	private static final long serialVersionUID = 1L;

	public CreateJTextFieldWithBorder() {

		// set flow layout for the frame
		this.getContentPane().setLayout(new FlowLayout());

		// create JTextField
		JTextField field = new JTextField(20);
		field.setText("Java Code Geeks");

		//  create a line border with the specified color and width
		Border border = BorderFactory.createLineBorder(Color.BLUE, 5);

		// set the border of this component
		field.setBorder(border);

		// add textfield to frame
		add(field);

	}

	private static void createAndShowGUI() {

  //Create and set up the window.

  JFrame frame = new CreateJTextFieldWithBorder();

  //Display the window.

  frame.pack();

  frame.setVisible(true);

  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

	public static void main(String[] args) {

  //Schedule a job for the event-dispatching thread:

  //creating and showing this application's GUI.

  javax.swing.SwingUtilities.invokeLater(new Runnable() {

public void run() {

    createAndShowGUI(); 

}

  });
    }

}
