对于我的Java II类，我们正在编写一个程序，使EmployeeManager能够使用测试程序以及教师提供的4个类程序。但是，我遇到了一些获得正确输出的问题。
public class mcshonsey_EmployeeManager
{
final int EMPLOYEE_MAX = 15;
Employee[] employees = new Employee[EMPLOYEE_MAX];
int currentEmployees;
public mcshonsey_EmployeeManager()
{
employees = new Employee[this.getEmployeeMax()];
currentEmployees = 0;
}
public int getEmployeeMax()
{
return this.EMPLOYEE_MAX;
}
public void setCurrentEmployees(int currentEmployees)
{
this.currentEmployees = currentEmployees;
}
public int getCurrentEmployees()
{
return this.currentEmployees;
}
public void addEmployee(int type, String firstName, String lastName, char mI, char gender, int employeeNumber, boolean fulltime, double amount)
{
if (this.getCurrentEmployees() < 15);
{
setCurrentEmployees(getCurrentEmployees() + 1);
}
if (this.getCurrentEmployees() == 15);
{
System.out.println("Maximum number of Employees reached. Employee " + employeeNumber + " not added. ");
}
if (type == 1)
{
employees[this.getCurrentEmployees()] = new HourlyEmployee(firstName, lastName, mI, gender, employeeNumber, fulltime, amount);
}
else if (type == 2)
{
employees[this.getCurrentEmployees()] = new SalaryEmployee(firstName, lastName, mI, gender, employeeNumber, fulltime, amount);
}
else
{
employees[this.getCurrentEmployees()] = new CommissionEmployee(firstName, lastName, mI, gender, employeeNumber, fulltime, amount);
}
}
public void removeEmployee(int index)
{
do
{
employees[index] = employees[14];
this.currentEmployees = currentEmployees;
currentEmployees += -1;
} while (index <= this.currentEmployees);
}
public void listAll()
{
if (this.currentEmployees == 0)
{
System.out.print("None \n");
}
else
{
for (int x = 0; x < employees.length; x++)
{
if (employees[x] != null)
{
System.out.println(employees[x]);
}
}
}
}
public void listHourly()
{
int a = 0;
for (int x = 0; x < employees.length; x++)
{
if (employees[x] instanceof HourlyEmployee)
{
a += 1;
System.out.println(employees[x]);
}
}
if (a == 0)
{
System.out.print("None \n");
}
}
public void listSalary()
{
int a = 0;
for (int x = 0; x < employees.length; x++)
{
if (employees[x] instanceof SalaryEmployee)
{
a += 1;
System.out.println(employees[x]);
}
}
if (a == 0)
{
System.out.print("None \n");
}
}
public void listCommission()
{
int a = 0;
for (int x = 0; x < employees.length; x++)
{
if (employees[x] instanceof CommissionEmployee)
{
a += 1;
System.out.println(employees[x]);
}
}
if (a == 0)
{
System.out.print("None \n");
}
}
public void resetWeek()
{
for (int x = 0; x < currentEmployees; x++)
{
employees[x].resetWeek();
}
}
public double calculatePayout()
{
double totalPay = 0.0;
double y = 0.0;
for (int x = 0; x < currentEmployees; x++)
{
y = employees[x].calculateWeeklyPay();
totalPay += y;
}
return totalPay;
}
public void removeRedundancies()
{
}
public int getIndex(int employeeNumber)
{
int index = 0;
int y;
for (int x = 0; x < currentEmployees; x++)
{
y = employees[x].getEmployeeNumber();
if (y == employeeNumber)
{
index = x;
x = 1000;
}
else
{
index = -1;
}
}
return index;
}
public void sortNumber()
{
Employee[] employees2 = new Employee[1];
int aindex;
int bindex;
int [] employeeNumbers = new int[currentEmployees];
boolean flag = true;
for (int x = 0; x < currentEmployees; x++)
{
employeeNumbers[x] = employees[x].getEmployeeNumber();
}
while(flag)
{
flag = false;
int temporary;
for (int b = 0; b < currentEmployees; b++)
{
if (employeeNumbers[b] > employeeNumbers[b+1])
{
temporary = employeeNumbers[b];
employeeNumbers[b] = employeeNumbers[b+1];
employeeNumbers[b+1] = temporary;
flag = true;
}
}
}
for (int b = 0; b < currentEmployees; b++)
{
aindex = getIndex(employeeNumbers[b]);
bindex = b;
employees2[0] = employees[b];
employees[b] = employees[aindex];
employees[aindex] = employees2[0];
}
}
public void sortName()
{
Employee[] employee2 = new Employee[1];
int aindex;
int bindex;
String [] names = new String[currentEmployees];
for (int b = 0; b < currentEmployees; b++)
{
for (int c = b + 1; c < currentEmployees; c++)
{
if (employees[c].getLastName().compareTo(employees[b].getLastName()) < 0)
{
employee2[0] = employees[b];
employees[b] = employees[c];
employees[c] = employee2[0];
}
}
}
}
public void annualRaise()
{
for(int x = 0; x < currentEmployees; x++)
{
employees[x].annualRaise();
}
}
public double holidayBonuses()
{
double bonus = 0.0;
for (int x = 0; x < currentEmployees; x++)
{
bonus += employees[x].holidayBonus();
}
return bonus;
}
public void increaseHours(int index, double amount)
{
for (Employee currentEmployees: employees)
{
if (currentEmployees instanceof HourlyEmployee)
{
((HourlyEmployee) employees[index]).increaseHours(amount);
}
}
}
public void increaseSales(int index, double amount)
{
for (Employee currentEmployees: employees)
{
if (currentEmployees instanceof CommissionEmployee)
{
((CommissionEmployee) employees[index]).increaseSales(amount);
}
}
} }
现在，代码编译得很好，并且运行良好。但是，运行它会产生这样的结果：
List of all employees, HourlyEmployees, SalaryEmployees and CommissionEmployees:
None
None
None
None

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 15

（新产品）
哪个，不是正确的输出。在转移添加员工之前，没有人应该出现4次，只应列出一名员工不要添加。
我真的很难解决这个问题，以使其正常工作。我该如何解决这个问题？
编辑：显示错误的第64行是：
employees[this.getCurrentEmployees()] = new SalaryEmployee(firstName, lastName, mI, gender, employeeNumber, fulltime, amount);
再次编辑：这是main（）方法，EmployeeManagerTest。

再次编辑：我的导师给出了一些修复建议，并且我已经更新了它现在提供的代码和输出。
