public class GuessBirthdayUsingConfirmationDialog {
    public static void main(String[] args) {
         int day=0;
         int answer;
         int[][][] dates = {
                 {{ 1,  3,  5,  7},{ 9, 11, 13, 15},{17, 19, 21, 23},{25, 27, 29, 31}},
                 {{ 2,  3,  6,  7},{10, 11, 14, 15},{18, 19, 22, 23},{26, 27, 30, 31}},
                 {{ 4,  5,  6,  7},{12, 13, 14, 15},{20, 21, 22, 23},{28, 29, 30, 31}},

                 {{16, 17, 18, 19},{20, 21, 22, 23},{24, 25, 26, 27},{28, 29, 30, 31}}};
        Scanner input = new Scanner(System.in);
        for (int i = 0; i < 5; i++) {
            System.out.println("Is your birthday in Set " + (i + 1) + "?");
            for (int j = 0; j < 4; j++) {
                for (int k = 0; k < 4; k++) {
                    System.out.printf("%4d", dates[i][j][k]);
                }
                System.out.println();
            }
            System.out.print("\nEnter 0 for No and 1 for Yes: ");
            answer =input.nextInt();
            if(answer==1){
                day += dates[i][0][0];
            }
        }
        System.out.print("你的生日是 "+day+"号!");
    }
}

 

第二种方式（出现选择窗口）

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

        int day=0;

        int answer= JOptionPane.showConfirmDialog(null,

        if (answer==JOptionPane.YES_OPTION)day+=1;

        answer= JOptionPane.showConfirmDialog(null,
