如何更改JOptionPane的背景颜色？

通过使用

UIManager

 import javax.swing.UIManager; UIManager UI=new UIManager(); UI.put("OptionPane.background",new ColorUIResource(255,0,0)); UI.put("Panel.background",new ColorUIResource(255,0,0));

要么

 UIManager UI=new UIManager(); UI.put("OptionPane.background", Color.white); UI.put("Panel.background", Color.white); JOptionPane.showMessageDialog(null,"Text","SetColor",JOptionPane.INFORMATION_MESSAGE);
