我必须将用户输入的内容与名称数组进行比较,如果是,则返回true,否则返回false到目前为止我有这个
public static boolean employeeReport(Employee[] emp, String[] lastName) throws IOException
{
System.out.println("Type out the last name of the employee you are looking for: ");
Scanner scan = new Scanner (System.in);
String Name = scan.next();
// ...
}
我正在考虑制作一个for循环并将“Name”与我拥有的String数组的每个单独值进行比较。有什么帮助吗?

将所有员工姓名插入
Set<String> set
然后只需检查
set.contains(name) //return true if exists and false if not

假设您有一个包含员工姓名的String数组,例如:
String[] nameBook;
你可以这样做:
public static boolean employeeReport(Employee[] emp, String[] lastName) throws IOException
{
System.out.println("Type out the last name of the employee you are looking for: ");
Scanner scan = new Scanner (System.in);
String name = scan.next();
//loop through the array and compare against entered name
for(String n : nameBook) {
if (n.equals(name)) return true;
}
return false;
}
请注意,根据Java约定,变量名称应以小写字母开头(我已在您的代码中对其进行了更正)。
