Java子类的最后一个实例覆盖值

我是一个涉及Java（又）的Web开发人员，我遇到了一些问题。Java子类的最后一个实例覆盖值

基本上，我有一个超类员工有两个子类扩展它称为管理和程序员。 Employee类包含一个基本上是Employee对象数组的employees数组。

下面是两个类（员工和管理）和最终主要方法的重要摘要。我会在底部解释输出。

public class **Employee** { 

    private static String firstName; 
    protected static int MAXEMPLOYEES = 5; 
    protected Employee[] employees = new Employee[MAXEMPLOYEES]; 
    protected int totEmployees = 0; 

    public Employee(String first) { 
     setFirstName(first); 
    } 

    public void setFirstName(String str){ 
     firstName = str; 
    } 

    public String getFirstName(){ 
     return firstName; 
    } 

    public boolean addEmployee(String fname) { 
     boolean added = false; 
     if (totEmployees < MAXEMPLOYEES) { 
      Employee empl = new Employee(fname); 
      employees[totEmployees] = empl; 
      added = true; 
      totEmployees++; 
     } 
     return added; 
    } 

} 

public class **Management** extends **Employee** { 
    private String title = "Project Manager"; 

    public Management(String fname, String t){ 
     super(fname); 
     title = t; 
    } 

    public boolean addManagement(String fname, String t){ 
     boolean added = false; 

     if (totEmployees < MAXEMPLOYEES) { 
      employees[totEmployees] = new Management(fname, t); 
      added = true; 
      totEmployees++; 
     } 
     return added; 
    } 
} 

------------------------------------- 
package employee; 

public class EmployeeApplication { 

    public static void main(String[] args) { 
     Employee[] empl = new Employee[3]; 
     empl[0] = new Employee("Kyle"); 
     empl[1] = new Management("Sheree", "Director"); 

     System.out.println(empl[0].getFirstName()); 
    } 
}

现在，我期望系统打印出“Kyle”，但它打印出“Sheree”。有任何想法吗？？？
