我是Java的新手 . 我需要一些帮助，使用循环接受其他用户输入，直到用户输入结束输入的值 . 我的问题从语句“System.out.println(”你完成了吗？输入大写的Y / N)开始 . 下面是我的代码 .

公共类EmployeeData {

//declare variables

private String firstName;

private String lastName;

private int id;

private double hourlyWage;

//constructors

public EmployeeData(String firstName, String lastName, int id, double hourlyWage){

this.firstName = firstName;

this.lastName = lastName;

this.id = id;

this.hourlyWage = hourlyWage;

}

// getters and setters

public String getFirstName() {

return firstName;

}

public void setFirstName(String firstName) {

this.firstName = firstName;

}

public String getLastName() {

return lastName;

}

public void setLastName(String lastName) {

this.lastName = lastName;

}

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public double getHourlyWage() {

return hourlyWage;

}

public void setHourlyWage(double hourlyWage) {

this.hourlyWage = hourlyWage;

}

//method to return string

public String toString(){

return "Employee Name: " + this.firstName +" "+ this.lastName + "\n"+ "Employee ID: " +this.id + "\n"+ "Hourly Wage "+ this.hourlyWage;

}

}

import java.util.Scanner;

公共类员工{
