Set background color in JLabel

With this example we shall show you how to set background color in a JLabel component in Java Desktop Applications. This will enrich and customize your GUI components.

It’s very easy to set the background color in a JLebel, as all you have to do is:

  • Create a class that extends JFrame.
  • Create a new JLabel.
  • Use JLabel.setBackground(Color.[COLOR_CODE]) to set the foreground color.
  • Use add method to add the JLabel to the frame.

 
Let’s see the code snippet that follows:

package com.javacodegeeks.snippets.desktop;

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

import javax.swing.JFrame;
import javax.swing.JLabel;

public class SetBackgroundColorInJLabel extends JFrame {

	private static final long serialVersionUID = 1L;

	public SetBackgroundColorInJLabel() {

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

		JLabel label = new JLabel("Java Code Geeks - Java Examples");

		// if true the component paints every pixel within its bounds
		label.setOpaque(true);

		// sets the background color of this component
		// the background color is used only if the component is opaque
		label.setBackground(Color.BLUE);

		// add label to frame
		add(label);

	}

	private static void createAndShowGUI() {

  //Create and set up the window.

  JFrame frame = new SetBackgroundColorInJLabel();

  //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(); 

}

  });
    }

}
