我是Java的新手 . 我需要一些幫助，使用循環接受其他用戶輸入，直到用戶輸入結束輸入的值 . 我的問題從語句“System.out.println(”你完成了嗎？輸入大寫的Y / N)開始 . 下面是我的代碼 .

公共類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;

公共類員工{

public static void main(String[] args){

String firstName;

String lastName;

int id;

double hourlyWage;

Scanner input = new Scanner(System.in);

System.out.println("Enter your First Name");

firstName = input.nextLine();

System.out.println("Enter your Last Name");

lastName = input.nextLine();

System.out.println("Enter your ID Number");

id = input.nextInt();

System.out.println("Enter your Hourly Wage");

hourlyWage = input.nextDouble();

EmployeeData em1 = new EmployeeData("firstName" , "lastName" , id, hourlyWage);

em1.setFirstName(firstName);

em1.setLastName(lastName);

em1.setId(id);

em1.setHourlyWage(hourlyWage);

String x = em1.toString();

System.out.println(x);

System.out.println("Are you are finished? Enter Y/N in uppercase");

char c = input.next().charAt(0);

if(c == 'N'){

System.out.println("Enter your First Name");

firstName = input.nextLine();

System.out.println("Enter your Last Name");

lastName = input.nextLine();

System.out.println("Enter your ID Number");

em2.setFirstName(firstName);

em2.setLastName(lastName);

em2.setId(id);

em2.setHourlyWage(hourlyWage);

String z = em2.toString();

System.out.println(z);

}

else{

System.out.println("You have finished.");

}

}

}
