Question

我是编程方面的新手，我是第一堂课，下周我们有一个项目。现在，我知道我的代码中有很多东西可以修复，但我想弄清楚为什么它不会让我输入ssn。这是我到目前为止运行它的程序：

本月：10

当前周：2

员工人数：3

员工资料＃1

薪酬类型（每小时（h），薪水，薪水加佣金（c））：h

姓名：Biff Sanchez

社会安全号码：生日月（1-12）：

在我要求输入生日月之前，我无法输入社会安全号码。我尝试过nextLine而不是next，但它没有改变任何东西。

我的代码如下，请帮忙。谢谢你！

Answer 1

问题出在名称的输入而不是SSN中。

更改此

    name[i] = kybd.next();

到

    name[i] = kybd.nextLine();

由于输入名称可以包含空格，因此您需要在此处使用nextLine。

Answer 2

我在没有使用nextLine（）的情况下找到了解决方案，由于某些原因，我遇到了麻烦。

    //get name
    System.out.print("Name: ");
    String nameF = kybd.next();
    String nameL = kybd.next();
    name[i] = nameF + nameL

忽略该用户需要输入String
