虽然这道题是书上的原题，但是感觉挺有趣的，将它敲了下来，然后运行进行了测试，果然很准啊。

还有一种用消息框来做的，一下子就有了测试软件的感觉了。

import javax.swing.JOptionPane;
public class Main
{
public static void main(String[] args)
{

String set1 =
" 1 3 5 7\n"+
" 9 11 13 15\n"+
"17 19 21 23\n"+
"25 27 29 31";

String set2 =
" 2 3 6 7\n"+
"10 11 14 15\n"+
"18 19 22 23\n"+
"26 27 30 31";

String set3 =
" 4 5 6 7\n"+
"12 13 14 15\n"+
"20 21 22 23\n"+
"28 29 30 31";

String set4 =
" 8 9 10 11\n"+
"12 13 14 15\n"+
"24 25 26 27\n"+
"28 29 30 31";

String set5 =
"16 17 18 19\n"+
"20 21 22 23\n"+
"24 25 26 27\n"+
"28 29 30 31";

int day=0;

int answer = JOptionPane.showConfirmDialog(null,"Is your birthday in these numbers?\n" + set1);
if (answer == JOptionPane.YES_OPTION)
day += 1;

answer = JOptionPane.showConfirmDialog(null,"Is your birthday in these numbers?\n" + set2);
if (answer == JOptionPane.YES_OPTION)
day += 2;

answer = JOptionPane.showConfirmDialog(null,"Is your birthday in these numbers?\n" + set3);
if (answer == JOptionPane.YES_OPTION)
day += 4;

answer = JOptionPane.showConfirmDialog(null,"Is your birthday in these numbers?\n" + set4);
if (answer == JOptionPane.YES_OPTION)
day += 8;

answer = JOptionPane.showConfirmDialog(null,"Is your birthday in these numbers?\n" + set5);
if (answer == JOptionPane.YES_OPTION)
day += 16;
JOptionPane.showMessageDialog(null,"Your birthday is " + day + "!");
}
}
