Set Color in JOptionPane

     

In this section, you will learn how to set color in JOptionPane. Now to do this, we have used UIManager class which is responsible for look and feel. Using following key value pair, we have set the background color for JOptionPane and Panel.

um.put("OptionPane.background",Color.yellow);
um.put("Panel.background",Color.yellow);

Here is the code:

import java.awt.*;
import javax.swing.*;
public class SetColor{
public static void main(String[]args){
 UIManager um=new UIManager();
 um.put("OptionPane.background",Color.yellow);
 um.put("Panel.background",Color.red);
 JOptionPane.showMessageDialog(null,"Hello","Set Color",
   JOptionPane.INFORMATION_MESSAGE
);
}
}
