You can do it by directly specifying the Look and Feel of your message.
您可以通过直接指定消息的外观来实现。
Your code will take the default one, while this one will use the "PLAIN_MESSAGE" style, which lacks the icon. The behaviour of the component remains unchanged.
您的代码将采用默认代码，而此代码将使用缺少图标的“PLAIN_MESSAGE”样式。组件的行为保持不变。
JOptionPane.showConfirmDialog(null, label, "ScreenPreview", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);

This is fairly easy by using a transparent icon as below (as opposed to the black 'splash image'). Though note that while option pane offers some 'wiggle space' in terms of how it is displayed, go to change a couple of things and it quickly becomes easier to use a JDialoginstead.
通过使用如下的透明图标（而不是黑色的“初始图像”），这相当容易。尽管请注意，虽然选项窗格在显示方式方面提供了一些“摆动空间”，但要更改一些内容，使用 a 很快就会变得更容易JDialog。
import java.awt.*;
import java.awt.image.BufferedImage;
import javax.swing.*;
class IconFree {
public static void main(String[] args) {
Runnable r = new Runnable() {
@Override
public void run() {
// A transparent image is invisible by default.
Image image = new BufferedImage(
1, 1, BufferedImage.TYPE_INT_ARGB);
JPanel gui = new JPanel(new BorderLayout());
// ..while an RGB image is black by default.
JLabel clouds = new JLabel(new ImageIcon(new BufferedImage(
250, 100, BufferedImage.TYPE_INT_RGB)));
gui.add(clouds);
JOptionPane.showConfirmDialog(null, gui, "Title",
JOptionPane.OK_CANCEL_OPTION,
JOptionPane.QUESTION_MESSAGE,
new ImageIcon(image));
}
};
// Swing GUIs should be created and updated on the EDT
// http://docs.oracle.com/javase/tutorial/uiswing/concurrency/initial.html
SwingUtilities.invokeLater(r);
}
}

Write -1 in place of JOptionPane.QUESTION_MESSAGE.
用 -1 代替JOptionPane.QUESTION_MESSAGE.
