Equipment接口

包括：Equipment接口

PC、noteBook、Printer三个实现类

该接口实现类的创建：(快捷方法)

1. implements接口，添加私有属性
2. alt+shift+s->generate Setters and Getters 全选 创建属性调用方法
3. alt+shift+s->generate constructor using Fields 分别创建带参和不带参的构造函数
4. 实现接口的抽象方法，可利用报错处自动创建并修改

Equipment.java

package com.atguigu.team.domain;

public interface Equipment {
	String getDescription();//默认是抽象方法
}

PC.java

package com.atguigu.team.domain;

public class PC implements Equipment{

	private String model;//机器型号
	private String display;//显示器名称

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

		this.display = display;
	}

	@Override
	public String getDescription() {
		// TODO Auto-generated method stub
		return model+"("+display+")";
	}

}

NoteBook.java

		this.model = model;

}

Printer.java

package com.atguigu.team.domain;

Employee类及其子类

完成employee相关类的创建

• employee 员工类，父类，包括id,name,age,salary四个基本属性
• programmer 程序员类，继承自employee类，从程序员开始可以被添加到团队中，拥有memberId、staus、equipment基本属性
• designer 设计师类，继承自employee类，从设计师开始有奖金，拥有bonus基本属性
• Architect 架构师类，继承自设计师类，从架构师开始有奖金，拥有block基本属性
• status 状态类，是一个枚举类，表示员工状态，包括BUSY、FREE、VOCATION三种状态
