所以我有这段代码:
$q = mysqli_query($connection ,"insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'longitude','30');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'latitude','30');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'tagline','doctor');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'verify_user','on');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'contact_form','off');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'first_name','$doctor_name');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'address','$address');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'phone_number','$mobile');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'nickname','$doctor_name');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'user_type','professional');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'profile_status','active');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'directory_type','127');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'user_profile_specialist','$specialicity');
insert into wp_abzj_usermeta (user_id,meta_key,meta_value) VALUES ($last_id,'$specialicity','$specialicity')
");
所以到现在为止,我应该有一个菜单,它将在用户输入中读取,直到用户键入0.但是,我不希望用户输入0(整数)退出,而是希望代码在用户输入时停止' X' (一个人物)。有没有办法做到这一点?我是Java的新手。
答案 0 :(得分:0)
您可以使用nextInt()
而不是next()
。因此,您的选择需要定义为String。在此之后,即使输入1或2之类的数字,这些数字也将作为字符串处理。之后,您可以使用" 1"和#34; x"。
答案 1 :(得分:0)
您应该使用scanner.nextLine().charAt(0)
而不是scanner.next().charAt(0)
,因为接下来不会使用换行符并且可以跳过您的新输入
答案 2 :(得分:0)
似乎你想接受混合输入,包括文本(" x")和整数。
hasNextLine()
类有一些实用程序方法可以在使用之前检测扫描程序输入,例如hasNextInt()
或if (scanner.hasNextInt()) {
// It's an integer
int choice = scanner.nextInt();
switch (choice) {
...
}
}
else {
// A scanner input is always parseable as a string
String choice = scanner.nextLine();
if (Objects.equals(choice, "x")) {
// Stop, exit, return, terminate and abort
}
else {
// What happens if the user entered an invalid string?
// You decide!
}
}
。使用这些方法,您可以轻松检测是否输入了有效的菜单选项:
Scanner scanner = new Scanner(int);
while (scanner.hasNext()) {
...
}
每次迭代,您都会创建一个新的Scanner实例。这是不必要的开销。您最好只创建一个扫描仪,然后重复接受输入:

您应该正确格式化代码。错误的缩进很容易让其他读者感到困惑,包括你自己。
