嘿,我有一个 EmployeeStore,为此我使用了哈希图。地图存储的变量是电子邮件名称和 ID。我有一个名为 SearchByEmail 的方法,但这有一个问题。当用户在 UI 中输入正确的员工电子邮件时,该方法返回 false。
这是我的代码:这是在 MainApp
case 2:
System.out.println("Search by Email.");
Employee employeeSearchEmail = MenuMethods.userInputByEmail();
Store.searchByEmail(employeeSearchEmail.getEmployeeEmail());
菜单方法
//Imports
import java.util.Scanner;
//********************************************************************
public class MenuMethods
{
private static Scanner keyboard = new Scanner(System.in);
//Methods for the Company Application menu.
//Method for validating the choice.
public static int getMenuChoice(String menuString, int limit, String prompt, String errorMessage)
{
System.out.println(menuString);
int choice = inputAndValidateInt(1, limit, prompt, errorMessage);
return choice;
}
//********************************************************************
//This method is used in the getMenuChoice method.
public static int inputAndValidateInt(int min, int max, String prompt, String errorMessage)
{
int number;
boolean valid;
do {
System.out.print(prompt);
number = keyboard.nextInt();
valid = number <= max && number >= min;
if (!valid) {
System.out.println(errorMessage);
}
} while (!valid);
return number;
}
//********************************************************************
public static Employee userInput()
{
String temp = keyboard.nextLine();
Employee e = null;
System.out.println("Please enter the Employee Name:");
String employeeName = keyboard.nextLine();
System.out.println("Please enter the Employee ID:");
int employeeId = keyboard.nextInt();
temp = keyboard.nextLine();
System.out.println("Please enter the Employee E-mail address:");
String employeeEmail = keyboard.nextLine();
return e = new Employee(employeeName , employeeId, employeeEmail);
}
//********************************************************************
public static Employee userInputByName()
{
//String temp is for some reason needed. If it is not included
//The code will not execute properly.
String temp = keyboard.nextLine();
Employee e = null;
System.out.println("Please enter the Employee Name:");
String employeeName = keyboard.nextLine();
return e = new Employee(employeeName);
}
//********************************************************************
public static Employee userInputByEmail()
{
//String temp is for some reason needed. If it is not included
//The code will not execute properly.
String temp = keyboard.nextLine();
Employee e = null;
System.out.println("Please enter the Employee Email:");
String employeeEmail = keyboard.nextLine();
//This can use the employeeName's constructor because java accepts the parameters instead
//of the name's.
return e = new Employee(employeeEmail);
}

通过电子邮件搜索
public boolean searchByEmail(String employeeEmail)
{
//(for(Employee e : map.values()) {...})
//and check for each employee if his/her email matches the searched value
boolean employee = map.equals(employeeEmail);
System.out.println(employee);
return employee;
