如何根据员工所属的部门将Employee对象加载到Departments的ArrayList中？

标签： java

我需要帮助！我必须完成Java评估才能进入这个Java培训计划，我的未来取决于此！以下是评估的条款： 2.使用以下属性/变量创建Employee类：     名称     年龄     系

  1. 创建一个名为Department的类，其中包含一个员工列表。 a）部门课程将有一种方法，将按年龄命令退还其员工。 b）department的值只能是以下值之一：     “会计”     “市场营销”     “人力资源”     “信息系统”

  2. 在名为PrimeAgeChecker的单独类中创建静态方法，以检查员工的年龄是否为素数。此方法应该能够接受雇员对象作为参数进行检查。

  3. 创建一个名为Company的类，其中包含一个部门列表。在此类中创建一个main方法，以将以下部门和相应的员工信息加载到公司中：

    4. 我确实每天和每晚都在研究这个问题大约一个半星期，但还没有想到它。以下是我到目前为止的情况：

    package JAssessment;



public class Employees {
//fields
private String name; 
private int age;
public String employees;
public String department;

public String getDepartment(){
        return department;
    }
public Employees() 
{
    name = "unknown name";
    age = 3;
}
public void setAge(int age)
{
    this.age = age;
}
public int getAge() 
{
    return age;
}
public void setName(String name)
{
    this.name = name;
}
public String getName()
{
    return name;
}
public String toString()
{
    return this.getName() + " (" + this.getAge() + " Age)";
}
public void setDepartment(String d1) {
    this.department = d1;

}
public void setDeptName(String string) {
    string = string;

}   

}


package JAssessment;

    String department;

    public Department(String String) {
    this.deptName = deptName;

}

public String getDeptName() {
    return deptName;
}

public void setDeptName(String deptName) {
    this.deptName = deptName;
}

public static void addEmployeeX(Employees e)
{   
    //put the employee age's in ascending order
    if (employees.isEmpty())
    {
    employees.add(e);
    }
    else
    {
        int i;
    for (i = 0; i < employees.size(); i++)
    {
        if (employees.get(i).getAge() > e.getAge())
        {
        employees.add(i, e);
        break;
        }
        }

        }   

    }

    1. 我遇到的第一个问题是试图弄清楚如何将Employees ArrayList中的Employees加载到Department ArrayList中属于他们所属的Departments中。这一切都应该在公司类中进行。

    2. 我遇到的第二个问题是试图找出如何运行属于＆＃34; Accounting＆＃34;部门和＆＃34;信息系统＆＃34;部门通过部门类中的addEmployeesX方法。这也应该在公司课程中完成。

      3. 我会接受任何我能得到的帮助。我现在非常绝望，时间正在逐渐消失。感谢您抽出宝贵时间阅读我的帖子并获得任何帮助！
