ねえ、私はこれにハッシュマップを使用したEmployeeStoreを持っています。マップが格納する変数は、電子メールの名前とIDです。SearchByEmailというメソッドがありますが、これに問題があります。ユーザーが正しい従業員の電子メールをUIに入力すると、このメソッドはfalseを返します。
これが私のコードです:これはMainAppにあります
case 2:
System.out.println("Search by Email.");
Employee employeeSearchEmail = MenuMethods.userInputByEmail();
Store.searchByEmail(employeeSearchEmail.getEmployeeEmail());
MenuMethods
//Imports

//Methods for the Company Application menu.
//Method for validating the choice.

{
System.out.println(menuString);
int choice = inputAndValidateInt(1, limit, prompt, errorMessage);
return choice;

public static int inputAndValidateInt(int min, int max, String prompt, String errorMessage)

valid = number <= max && number >= min;
if (!valid) {
System.out.println(errorMessage);

} while (!valid);
return number;
