public static void main(String[] args)
{
String[] option = {"Chorita M. Adlawan", "Noel B. Angeles", "Julie P. Benenoso", "Percival P.Bermas",
"Beverly Mae M. Brebante","Adela N. Cabaylo", "Carol G. Cainglet", "Oscar U. Cainglet",
String selected = (String)JOptionPane.showInputDialog(null, "MINES AND GEOSCIENCES BUREAU - REGION XI, DAVAO CITY\n" +

If you want all JOptionPanes to have the same font style and size, you can change the property of the UIManagerwith:
如果您希望所有JOptionPanes 具有相同的字体样式和大小，您可以更改UIManagerwith的属性：
javax.swing.UIManager.put("OptionPane.font", new Font("yourFontName", Font.BOLD, 30));
To get a list of the available font names, use the following snippet:
要获取可用字体名称的列表，请使用以下代码段：
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] fontNames = ge.getAvailableFontFamilyNames();
for (int index = 0; index < fontNames.length; index++)
{
System.out.println(fontNames[index]);
}

One of the easiest ways is to use HTML directly in the String literal. For example:
最简单的方法之一是直接在字符串字面量中使用 HTML。例如：
"MINES AND GEOSCIENCES BUREAU - REGION XI, DAVAO CITY\n"
"MINES AND GEOSCIENCES BUREAU - REGION XI, DAVAO CITY\n"
Can easily become:
很容易变成：
"<html><span style='font-size:2em'>MINES AND GEOSCIENCES BUREAU - REGION XI, DAVAO CITY"
"<html><span style='font-size:2em'>MINES AND GEOSCIENCES BUREAU - REGION XI, DAVAO CITY"
Note that when you use HTML, you can no longer use \nfor new lines. Use <br>instead.
请注意，当您使用 HTML 时，您不能再使用\n换行符。使用<br>来代替。
