我想其中應該採用以下格式文件的每一行改爲： -故障打印出的ArrayList如表到控制檯
name type hours wage salary
再行拆分成單獨的領域，做任何必要的轉換（從String到int或double）。然後我將使用靜態工廠方法創建SalariedEmployee/HourlyEmployee對象並將其添加到ArrayList。
我想循環員工列表並打印出一張表格，列出每個員工姓名，類型，工作時間和總工資的控制檯。每列需要對齊，字符串 - 左對齊，數字 - 右對齊。所有的錢欄應該有2個分位。然後我需要調用totalPay方法來計算員工的總工資。我還想保留所有員工的總工資總額，並將其顯示在底部的單獨行中。確保列與他們的標題對齊。我想使用System.out.printf格式化和顯示行。
的問題是我已經多次試圖打印出來的員工名單，但遇到錯誤
private static final String fileName = "input.txt";
public static void main(String[] args) {
List<Employee> employees = new ArrayList<>(); //
String line = null;
BufferedReader reader = null;
try{
reader = new BufferedReader(new FileReader(new File(fileName)));
while((line = reader.readLine()) != null){
String[] information = line.split("\\s+");
String name = information[0];
String type = information[1];
int hours;
hours = Integer.parseInt(information[2]);
double wage = Double.parseDouble(information[3]);
double salary = Double.parseDouble(information[4]);
employees.add(Employee.factory(name, type, hours, wage, salary));
}
reader.close();
} catch (IOException ex) {
System.out.println("Command-line argument is missing");
System.exit(1);
}
int size = employees.size();
System.out.println("Name Type Hours Total Pay");
for(int i =0; i < size; i++){
System.out.println(employees.getName() + " " +
employees.getType() + " " + employees.getHoursWorked() + " "
Employee.totalPay());
}
}
我父員工：
public abstract class Employee{
protected String name;
protected int hours;
public String getName(){
return name;
}
public int getHours(){
return hours;
}
public abstract String getType();
public Employee(String name, int hours){
this.name = name;
this.hours = hours;
}
public abstract double totalPay();
public static Employee factory(String name, String type, int hours, double
wage, double salary){
if(type.equals("Salaried") || type.equals("SALARIED") ||
type.equals("salaried")){
Employee object = new SalariedEmployee(name, hours, (int)salary);
return object;
}else if(type.equals("Hourly") || type.equals("HOURLY") ||
type.equals("hourly")){
Employee object = new HourlyEmployee(name, hours, (int)wage);
return object;
}else{
return null;
}
}
我的子類HourlyEmployee：
public class HourlyEmployee extends Employee {
private double wage; // wage per hour
private double hoursWorked; // hours worked for week
private int workedHours = (int)hoursWorked;
public HourlyEmployee(String name, double hourlyWage, int workedHours){
super(name, workedHours);
setWage(hourlyWage); // validate hourly wage
setHours(workedHours); // validate hours worked
}
public void setWage(double hourlyWage)
{
if (hourlyWage >= 0.0)
wage = hourlyWage;
else
throw new IllegalArgumentException("Hourly wage must be >= 0.0");
}
public double getWage()
{
return wage;
}
public void setHours(double hoursWorked)
{
if ((hoursWorked >= 0.0) && (hoursWorked <= 168.0))
this.hoursWorked = hoursWorked;
else
throw new IllegalArgumentException("Hours worked must be >= 0.0 and
<= 168.0");
}
public double getHoursWorked()
{
return hoursWorked;
}
@Override
public String getType(){
return "Hourly";
}
@Override
public double totalPay(){
return getWage() * getHours();
}
}
我的小類SalariedEmployee：
public class SalariedEmployee extends Employee {
private double salary; // wage per year
private double hoursWorked; // hours worked for week
private int workedHours = (int)hoursWorked;
public SalariedEmployee(String name, double salary, int workedHours){
super(name, workedHours);
setSalary(salary); // validate hourly wage
setHours(workedHours); // validate hours worked
}
public void setSalary(double employeeSalary)
{
if (salary >= 0.0)
salary = employeeSalary;
else
throw new IllegalArgumentException("Salary must be >= 0.0");
}
public double getSalary()
{
return salary;
}
public void setHours(double hoursWorked)
{
this.hoursWorked = hoursWorked;
}
public double getHoursWorked()
{
return hoursWorked;
}
@Override
public String getType() {
return "Salaried";
}
@Override
public double totalPay() {
return (getSalary())/52;
}
}
