推荐答案

如果希望所有JOptionPane具有相同的字体样式和大小，则可以使用以下方法更改UIManager的属性:

If you want all JOptionPanes to have the same font style and size, you can change the property of the UIManager with:

javax.swing.UIManager.put("OptionPane.font", new Font("yourFontName", Font.BOLD, 30));

要获取可用字体名称的列表，请使用以下代码段:

To get a list of the available font names, use the following snippet:

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] fontNames = ge.getAvailableFontFamilyNames();

for (int index = 0; index < fontNames.length; index++)
{
     System.out.println(fontNames[index]);
}
