The title in the

JOptionPane.showMessageDialog(this,"HI");

Will be “Massage” and I think this by default

Can I change the title and the color or the font of the message string = “HI“?

Hi javamate06

yes you can change the title, you should use this

public static void showMessageDialog(this, "HI", "My title", JOptionPane.INFORMATION_MESSAGE)

void javax.swing.JOptionPane.showMessageDialog(Component parentComponent, Object message, String title, int messageType, Icon icon) throws HeadlessException

You can change the title and icon of the message window, but not the fong and color. Font and color are part of the Look And Feel that you are using.

this represents the parent window. If you supply a parent, then the showd message will be modal to that parent. If you supply null, that displayed window will not have a parent.
