量化交易客户给api接口:项目开发团队分配管理软件

项目需求

service包下主要存放一些方法类，也就是实现对象的具体功能的一些方法。

模拟实现一个基于文本界面的《项目开发团队分配管理软件》

Programmer子类：


//程序员
public class Programmer extends Employee{
    private int memberId;
    private boolean status= true;
    private Equipment equipment;

    public Programmer(int id, String name, int age, double salary, Equipment equipment) {
        super(id, name, age, salary);
        this.equipment = equipment;
    }

    public Programmer() {
    }

    public int getMemberId() {
        return memberId;
    }

    public void setMemberId(int memberId) {
        this.memberId = memberId;
    }

    public boolean getStatus() {
        return status;
    }

    public void setStatus(boolean status) {
        this.status = status;
    }

    public Equipment getEquipment() {
        return equipment;
    }

    public void setEquipment(Equipment equipment) {
        this.equipment = equipment;
    }

    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() ;
    }
}

创建了两个异常类用来处理开发人员模块，和团队管理模块产生的异常。

团队组建成功，则可以进入项目模块，添加项目，分配开发团队进行开发。

TeamException异常类：

package 关卡12.service;

public class TeamException extends Exception{
    public TeamException() {
    }

    public TeamException(String message) {
        super(message);
    }

}

2service包下的程序

Architect子类：


public class Architect extends Designer {
    private int stock;

    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 Architect() {

    }

    public Architect(int id, String name, int age, double salary, double bonus, int stock) {
    }

    public int getStock() {
        return stock;
    }

    public void setStock(int stock) {
        this.stock = stock;
    }

    @Override
    public String getDetailsForTeam() {
        return getMemberDetails() + "	架构师	" +
                getBonus() + "	" + getStock();
    }

    @Override
    public String toString() {
        return getDetails() + "	架构师	" + getStatus() + "	" +
                getBonus() + "	" + getStock() + "	" + getEquipment().getDescription();
    }
}

Designer子类：


public class Designer extends Programmer{
    private double bonus;

    public Designer(int id, String name, int age, double salary, Equipment equipment, double bonus) {
        super(id, name, age, salary, equipment);
        this.bonus = bonus;
    }

    public Designer() {
    }

    public double getBonus() {
        return bonus;
    }

    public void setBonus(double bonus) {
        this.bonus = bonus;
    }

    public String getDetailsForTeam() {
        return getMemberDetails() + "	设计师	" + getBonus();
    }

    @Override
    public String toString() {
        return getDetails() + "	设计师	" + getStatus() + "	" +
                getBonus() +"			" + getEquipment().getDescription();
    }

}

项目开发团队分配管理软件

软件启动时，首先进入登录界面进行注册和登录功能。

ProjectService类用来实现项目管理的功能。

Equipment接口：

public interface Equipment {
    public abstract String getDescription();
}

人员添加成功后，根据菜单提示，基于现有的公司成员，组建一个开发团队以开发一个新的项目。

Employee以及Employee的子类主要重写了toString方法还有一些其他的显示方法。由于之前写的代码很少设计到在不同的包或者不同的类下显示对象的内容，所以toString方法的重写对我来说算是一个新颖的知识。

newException异常类：

package 关卡12.service;

public class newException extends Exception{
    public newException() {
    }
    public newException(String message){
        super(message);

     }
}

主要涉及以下知识点：类的继承性和多态性对象的值传递、接口static和final修饰符特殊类的使用：包装类、抽象类、内部类异常处理Java基本语法和流程控制数组，ArrayList集合

NoteBook实现类：


public class NoteBook implements Equipment {
    private String model;
    private double price;

    public NoteBook(String model, double price) {
        this.model = model;
        this.price = price;
    }

    public NoteBook() {
    }

    public String getModel() {
        return model;
    }

    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 + ")";
    }

}

TeamView类：

package 关卡12.view;

import 关卡12.domain.Employee;
import 关卡12.service.NameListService;
import 关卡12.service.TeamException;
import 关卡12.service.TeamService;
import 关卡12.service.newException;

3view包下的程序

PC实现类：

public class PC implements Equipment {
    private String model;
    private String display;

    public PC(String model, String display) {
        this.model = model;
        this.display = display;
    }

    public PC() {
    }

    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 + ")";
    }
}

熟悉Java面向对象的高级特性，进一步掌握编程技巧和调试技巧

组建过程包括将成员插入到团队中，或从团队中删除某成员，还可以列出团队中现有成员的列表，开发团队成员包括架构师、设计师和程序员。

然后可以对开发人员进行增删改操作

异常类

1domain包下的程序

编写各个模块的程序

domain包用来存放各种类，主要包含Employee和Equipment和他们的子类，用来构建开发人员的对象。

该软件实现以下功能：

Printer实现类：


public class Printer implements Equipment{
    private String name;
    private String type;

    public Printer(String name, String type) {
        this.name = name;
        this.type = type;
    }

    public Printer() {
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    @Override
    public String getDescription() {
        return name + "(" + type + ")";
    }

}

Employee父类：

public class Employee {
    private int id;
    private String name;
    private int age;
    private double salary;

    public Employee(int id, String name, int age, double salary) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.salary = salary;
    }

    public Employee(){

    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }

    @Override
    public String toString() {
        return getDetails();
    }
    protected String getDetails() {
        return id + "	" + name + "	" + age+ "		" +salary;
    }
}

1项目流程

Equipment设备接口包含3个实现类发，分别对应程序员、设计师、架构师的不同设备：NoteBook、PC、Printer。

当登陆成功后，进入菜单，首先就可以对开发人员账户和密码进行修改。

虽然整个程序编写晚用了很多时间，但是做项目才会知道自己的不足，知道自己的问题才会去克服问题，虽然整个过程很艰苦，但是自我能感觉到相比于之前，自己在Java编程上的进步真的很大。

编写的是账户管理模块的界面。

package 关卡12.view;

                System.out.println("输入长度（不大于" + limit + "）错误，请重新输入：");
                continue;
            }
            break;
        }

        return line;
    }

    //注册方法
