项目结构
在domain下建立
public interface Equipment {

}
public class NoteBook implements Equipment{
private String model;//机器的型号
private double price;//价格
public NoteBook() {
super();
}
public NoteBook(String model, double price) {

this.price = price;
}

}
public void setModel(String model) {
this.model = model;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
@Override
public String getDescription() {
return model + "(" + price + ")";
}
}
public class PC implements Equipment{
private String model;//机器型号
private String display;//显示器名称
public PC() {
super();
}
public PC(String model, String display) {
super();
this.model = model;
this.display = display;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
public String getDisplay() {
return display;
}
public void setDisplay(String display) {
this.display = display;
}
@Override
public String getDescription() {
return model + "(" + display + ")";
}
}
public class Printer implements Equipment{
private String name;//名称
private String type;//机器的类型
public Printer() {
super();
}

super();
this.name = name;
this.type = type;
}
public String getName() {
return name;
}
public void setName(String name) {

}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
@Override
public String getDescription() {
return name + "(" + type + ")";
}
}
public class Employee {
private int id;
private String name;
private int age;
private double salary;
public Employee() {
}
public Employee(int id, String name, int age, double salary) {
this.id = id;

}
protected String getDetails() {
return id + " " + name + " " + age+ " " +salary;
}
@Override
public String toString() {
return getDetails();
}
}
由于要用到Status，先去创建一个Status
public class Programmer extends Employee{
private int memberId;//员工号
private Status status = Status.FREE;
private Equipment equipment;
public Programmer(int id, String name, int age, double salary,Equipment equipment) {
super(id,name,age,salary);

}
public int getMemberId() {
return memberId;
}
public void setMemberId(int memberId) {
this.memberId = memberId;
}
public Status getStatus() {
return status;
}
public void setStatus(Status status) {
this.status = status;
}
public Equipment getEquipment() {
return equipment;
}
public void setEquipment(Equipment equipment) {
this.equipment = equipment;
}
}
public class Designer extends Programmer{ private double bonus;//奖金
public Designer(int id, String name, int age, double salary,
Equipment equipment,double bonus) {
super(id, name, age, salary, equipment);
this.bonus = bonus;
}
public double getBonus() {
return bonus;
}
public void setBonus(double bonus) {
this.bonus = bonus;
}
}
public class Architect extends Designer{ private int stock;//股票
public Architect(int id, String name, int age, double salary,
Equipment equipment, double bonus,int stock) {
super(id, name, age, salary, equipment, bonus);
this.stock = stock;
}
public int getStock() {
return stock;
}
public void setStock(int stock) {
this.stock = stock;
}
}
在service下创建
//表示员工的状态
public enum Status {
//空，忙，休假
FREE,BUSY,VOCATION;
}

}
}
public class TeamException extends Exception{
static final long serialVersionUID = -33875229948L;
public TeamException(){}
public TeamException(String message){
super(message);
}
}
在junit包中写个测试吧
public class NameListServiceTest {
@Test
public void testGetAllEmployees(){
NameListService listService = new NameListService();
Employee[] employees = listService.getAllEmployees();
for (int i = 0; i < employees.length; i++) {
System.out.println(employees[i]);
}
}
}
那么我们在之前的员工等类中加入方法并重写toString
Employee中
protected String getDetails() {
return id + " " + name + " " + age+ " " +salary;
}
@Override
public String toString() {
return getDetails();
}
Programmer中
protected String getMemberDetails() {
return getMemberId() + "/" + getDetails();
}
public String getDetailsForTeam() {
return getMemberDetails() + " 程序员";
}
@Override
public String toString() {
return getDetails() + " 程序员 " + status + " " + equipment.getDescription() ;
}
Designer中
public String getDetailsForTeam() {
return getMemberDetails() + " 设计师 " + getBonus();
}
@Override
public String toString() {
return getDetails() + " 设计师 " + getStatus() + " " +
getBonus() +" " + getEquipment().getDescription();
}
Architect中
public String getDetailsForTeam() {
return getMemberDetails() + " 架构师 " +
getBonus() + " " + getStock();
}
@Override
public String toString() {
return getDetails() + " 架构师 " + getStatus() + " " +
getBonus() + " " + getStock() + " " + getEquipment().getDescription();
}
在测试一下吧
在加一个测试方法
@Test
public void testGetAllEmployeeById() throws TeamException {
NameListService listService = new NameListService();
int id = 2;
Employee employee = listService.getEmployee(id);
System.out.println(employee);
}
继续写业务service下创建
