如何在扫描仪类的单行输入日月？ [英] How to enter day month year in single line for scanner class?

问题描述

扫描仪控制台=新扫描仪（System.in）;

System.out.print（输入生日（dd mm yyyy）老人：）;

int days = console.nextInt（）;

int months = console.nextInt（）;

int years = console.nextInt（）;

if（（days> = 30&& months> = 9&& years> = 1932）&&（天< = 30&&月< = 9&& years< = 1962））

System.out.println（>> ;>不符合每月支付的条件。原因：符合资格期后的差异）;

其他

{



System.out.println（>>>不符合每月付款的条件。原因：不是老人）;

}



我尝试过：



大家好，请指教。现在我的问题是我要键入3个数字，其中int天，月，年在单行扫描仪中，但不幸的是，当我按回车键时，程序将在int天数一次键入下一行。



i知道C程序允许在单行输入很多int数，但是java怎么样？谢谢你的建议。

Scanner console = new Scanner(System.in);
System.out.print("Enter birthdate (dd mm yyyy) of elderly: ");
int days = console.nextInt();
int months = console.nextInt();
int years = console.nextInt();
if ((days >= 30 && months >= 9 && years >= 1932) && (days <= 30 && months <= 9 && years <= 1962) )
System.out.println(">>> Not Eligible for monthly payout. Reason: Diasabilities after qualifying period");
else
{

System.out.println(">>> Not Eligible for monthly payout. Reason: Not an elderly" );
}

What I have tried:

Hi all, please advice me. now my problem is i want to key in 3 number which int days, months, years in single line of scanner, but unfortunately when i press enter, program will go to next line once key in number for int days.

i know that C program allow many int number input in single line, but how about the java? thanks for advice.

推荐答案

使用 Scanner.nextLine（） [ ^ ]读取完整的一行。但是，您需要使用 String 方法来分隔各个字段。

Use Scanner.nextLine()[^] to read a complete line. But you will then need to use String methods to separate the individual fields.
