java - 您好，我无法让 public String getGenderName() 输出用户输入的内容

Question

我无法让 public String getGenderName() 输出用户输入的内容。它只是不断输出错误输入。请帮助我，我对java有点陌生，所以请不要半解释。你我的代码有什么问题吗？请告诉我，如果有人知道如何实现公共(public)枚举性别，我也有兴趣看看您对此的看法

import java.text.NumberFormat;
import java.util.Scanner;

public class Employee {
private String firstName;
private String lastName;
private static String gender;
private int dependents;
private double annualSalary;
private NumberFormat nf = NumberFormat.getCurrencyInstance();
private static Scanner scan;
private static char sex;

public Employee() {     
    firstName = "not given";
    lastName = "not given";
    gender = "";
    dependents = 0;
    annualSalary = 20.000;      
}

public Employee(String first, String last, char sex, int dep, double salary) {
    setFirstName(first);
    setLastName(last);
    Character.toString(sex);;
    setDependents(dep);
    setAnnualSalary(salary);
}

public double calculatePay() {
    return annualSalary / 52;
}

public void displayEmployee() {
    System.out.println("First Name: " + getFirstName());
    System.out.println("Last Name: " + getLastName());
    System.out.println("Gender: " + getGenderName());
    System.out.println("Dependents: " + getDependents());
    System.out.println("Annual Salary: " + nf.format(getAnnualSalary()));        
    System.out.println("Weekly Pay: " + nf.format(calculatePay()));
}
public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getFirstName() {
    return firstName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public String getLastName() {
    return lastName;
}

***public String getGenderName()
{
       if ("m".equalsIgnoreCase(gender))
           return "Male";
        if ("f".equalsIgnoreCase(gender))
           return "Female";
       else 
           return "Wrong Input";
}***

public void setDependents(int dependents) {
    this.dependents = dependents;
}

public int getDependents() {
    return dependents;
}

public void setAnnualSalary(double annualSalary) {
    this.annualSalary = annualSalary;
}

public double getAnnualSalary() {
    return annualSalary;
}

public static void displayDivider(String outputTitle) {
    System.out.println("**************** " + outputTitle + " ****************");        
}

public static String getInput(String inputType) {
     System.out.println("Enter the " + inputType + ": ");
     scan = new Scanner(System.in);
     String input = scan.next();
     return input;
}   

public static void main(String[] args) {
    // Create an Employee object using the default constructor
    displayDivider("Create an Employee object using the default constructor");
    Employee employee1 = new Employee();
    Employee.setGender(Employee.gender);
    String input;
    int dependents;
    double annualSalary;
    input = getInput("First Name");
    employee1.setFirstName(input);
    input = getInput("Last Name");
    employee1.setLastName(input);
    input = getInput("Gender");
    setSex(input.charAt(0));
    Employee.setGender("gender");
    input = getInput("Dependents");
    dependents = Integer.parseInt(input);
    employee1.setDependents(dependents);
    input = getInput("Annual Salary");
    annualSalary = Double.parseDouble(input);
    employee1.setAnnualSalary(annualSalary);
    displayDivider("Employee Information");
    employee1.displayEmployee();
    displayDivider("Create a second Employee object using the multi-argument constructor");
    Employee employee2 = new Employee("John", "Doe", 'M', 3, 46000.0);
    displayDivider("Employee Information");
    employee2.displayEmployee();
}

private static void setGender(String string) {
    // TODO Auto-generated method stub

}

/**
 * @return the sex
 */
public static char getSex() {
    return sex;
}

/**
 * @param sex the sex to set
 */
public static void setSex(char sex) {
    Employee.sex = sex;
}
}

输出:

Enter the Annual Salary: 

Enter the First Name: 
g
Enter the Last Name: 
hhj
Enter the Gender: 
m
Enter the Dependents: 
7
Enter the Annual Salary: 
9
**************** Employee Information ****************
First Name: g
Last Name: hhj
Gender: **Wrong Input**
Dependents: 7
Annual Salary: $9.00
Weekly Pay: $0.17
**************** Sample Employee Information ****************
First Name: John
Last Name: Doe

Dependents: 3
Annual Salary: $46,000.00
Weekly Pay: $884.62

Answer 1

目前，您没有在构造函数中为gender 分配任何内容。你应该写:

gender = Character.toString(sex);

并且您的 setGender 方法为空

private static void setGender(String string) {
    // TODO Auto-generated method stub

}

它应该是:

public static void setGender(String string) {
    gender = string;

}

注意:您不应将性别保持为静态，这没有任何意义。
