Set Background Color in JLabel - Swing

Here is a sample tutorial to set background for a JLabel. By default, calling the setBackground(Color color) will not do the thing.



import javax.swing.*;
import java.awt.*;
class JLabelBackgroundDemo extends JFrame
{
JLabel l1,l2;
public JLabelBackgroundDemo()
{
setTitle("JLabel Background Demo");
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(400,400);
setLayout(new FlowLayout());
setVisible(true);
// Create labels
l1=new JLabel("I am first label");
l2=new JLabel("I am second label");
// Make opaque
l1.setOpaque(true);
l2.setOpaque(true);
// Then, set background
l1.setBackground(Color.cyan);
l2.setBackground(Color.pink);
// Add labels
add(l1);
add(l2);
}
public static void main(String args[])
{
new JLabelBackgroundDemo();
}
}
Notes: By default, the JLabel is not opaque, so you will have to make it opaque first in order to set a background for it.
