Java Swing Program to demonstrate JLabel with Text and Icon

Program

import javax.swing.*;
public class JLabelTextIconDemo
{
	public static void main(String args[])
	{
		JFrame frm = new JFrame("JLabel Demo");
		JLabel lblUserName, lblPassword;
		ImageIcon icoUserName, icoPassword;
		icoUserName = new ImageIcon("username.png");
		lblUserName = new JLabel();
		lblUserName.setText("User Name");
		lblUserName.setIcon(icoUserName);
		lblUserName.setBounds(0, 0, 150, 50);
		icoPassword = new ImageIcon("password.png");
		lblPassword = new JLabel();
		lblPassword.setText("Password");
		lblPassword.setIcon(icoPassword);
		lblPassword.setBounds(0, 50, 150, 50);
		frm.add(lblUserName);
		frm.add(lblPassword);
		frm.setSize(300, 300); 
		frm.setLayout(null);
		frm.setVisible(true);
		frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}
}

This Java Swing program demonstrates how to use a JLabel with both text and an icon in a graphical user interface (GUI). It displays two labels, each containing a combination of text ("User Name" and "Password") and an associated image icon.

1. Imports:

   • The javax.swing.* package is imported to utilize the JFrame, JLabel, and ImageIcon classes.

2. Creating the JFrame:

   • JFrame frm = new JFrame("JLabel Demo"): This creates a new window titled "JLabel Demo" using the JFrame class.
   • setSize(300, 300): This method sets the size of the frame to 300 pixels by 300 pixels.
   • setLayout(null): The null layout manager allows you to manually set the positions of components in the frame.
   • setVisible(true): Makes the frame visible on the screen.
   • setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE): Ensures that the program terminates when the window is closed.

3. Creating Image Icons:

   • ImageIcon icoUserName = new ImageIcon("username.png"): This loads an image (e.g., "username.png") as an icon.
   • ImageIcon icoPassword = new ImageIcon("password.png"): This loads another image (e.g., "password.png") for the second label.

4. Creating JLabel with Text and Icon:

   • lblUserName.setText("User Name"): This sets the text "User Name" for the first label.
   • lblUserName.setIcon(icoUserName): This sets the image icon (loaded from "username.png") to be displayed beside the text on the label.
   • lblPassword.setText("Password"): This sets the text "Password" for the second label.
   • lblPassword.setIcon(icoPassword): This sets the image icon (loaded from "password.png") for the second label.

5. Positioning the Labels:

   • setBounds(x, y, width, height): This method positions and sizes the labels within the frame.
     • The lblUserName label is placed at (0, 0) with width 150 and height 50.
     • The lblPassword label is placed at (0, 50) with width 150 and height 50.

6. Adding Labels to JFrame:

   • Both lblUserName and lblPassword are added to the frame using add().

7. Key Swing Methods Used:

   • JLabel(): Creates an empty label.
   • setText(String text): Sets the text for the label.
   • setIcon(Icon icon): Sets an image icon for the label.
   • setBounds(int x, int y, int width, int height): Positions and sizes the label.
   • add(Component component): Adds the label to the JFrame.
   • setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE): Specifies that the program should exit when the window is closed.
