一个找生日的小程序

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;
Scanner input = new Scanner(System.in);

System.out.print("Is your birthday in set1?\n");
System.out.print(set1);
System.out.print("\nEnter 0 for No and 1 for Yes： ");
int answer = input.nextInt();

if(answer == 1){
day += 1;
}

System.out.print("Is your birthday in set2?\n");
System.out.print(set2);
System.out.print("\nEnter 0 for No and 1 for Yes： ");
answer = input.nextInt();

if(answer == 1){
day += 2;
}

System.out.print("Is your birthday in set3?\n");
System.out.print(set3);
System.out.print("\nEnter 0 for No and 1 for Yes： ");
answer = input.nextInt();

if(answer == 1){
day += 4;
}

System.out.print("Is your birthday in set4?\n");
System.out.print(set4);
System.out.print("\nEnter 0 for No and 1 for Yes： ");
answer = input.nextInt();

if(answer == 1){
day += 8;
}

System.out.print("Is your birthday in set5?\n");
System.out.print(set5);
System.out.print("\nEnter 0 for No and 1 for Yes： ");
answer = input.nextInt();

if(answer == 1){
day += 16;
}

System.out.println("\nYour birthday is " + day + "!");
}

通过这个你可以确定测试人员的生日日期
