Cola公司的雇员分为以下若干类:(知识点:多态) [必做
题]
• 4.1 ColaEmployee :这是所有员工总的父类,属性:员工的
姓名,员工的生日月份。方法:getSalary(int month) 根据参数
月份来确定工资,如果该月员工过生日,则公司会额外奖励
100 元。
• 4.2 SalariedEmployee : ColaEmployee 的子类,拿固定工
资的员工。属性:月薪
课后作业
• 4.3 HourlyEmployee :ColaEmployee 的子类,按小时拿工
资的员工,每月工作超出160 小时的部分按照1.5 倍工资发
放。属性:每小时的工资、每月工作的小时数
• 4.4 SalesEmployee :ColaEmployee 的子类,销售人员,
工资由月销售额和提成率决定。属性:月销售额、提成率
• 4.5 定义一个类Company,在该类中写一个方法,调用该
方法可以打印出某月某个员工的工资数额,写一个测试类
TestCompany,在main方法,把若干各种类型的员工放在一
个ColaEmployee 数组里,并单元出数组中每个员工当月的
工资。
package week; public class ColaEmployee { protected String name; protected int months; protected int birthday; public ColaEmployee(String name, int months, int birthday) { super(); this.name = name; this.months = months; this.birthday = birthday; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getMonths() { return months; } public void setMonths(int months) { this.months = months; } public int getBirthday() { return birthday; } public void setBirthday(int birthday) { this.birthday = birthday; } public void getSalary(int month){ } }
package week; public class SalariedEmployee extends ColaEmployee { private double money; public SalariedEmployee(String name, int months, int birthday, double money) { super(name, months, birthday); if(super.getMonths()==super.getBirthday()){ System.out.println("员工"+name+months+"月的工资为"+(money+100)); }else{ System.out.println("员工"+name+months+"月的工资为"+money); } } }
package week; public class HourlyEmployee extends ColaEmployee{ private double hours; private int mon; public HourlyEmployee(String name, int months, int birthday, double hours, int mon) { super(name, months, birthday); this.hours=hours; this.mon=mon; if(super.getBirthday()!=super.getMonths()&&super.getMonths()>=160){ System.out.println("员工"+name+months+"月的工资为"+(mon*160+(hours-160)*mon*1.5)); }else if(super.getBirthday()==super.getMonths()&&super.getMonths()>=160){ System.out.println("员工"+name+months+"月的工资为"+(mon*160+(hours-160)*mon*1.5+100)); }else if(super.getBirthday()==super.getMonths()&&super.getMonths()<160) { System.out.println("员工"+name+months+"月的工资为"+(mon*hours+100)); }else if(super.getBirthday()!=super.getMonths()&&super.getMonths()<160) { System.out.println("员工"+name+months+"月的工资为"+mon*hours); } } }
package week; public class SalesEmployee extends ColaEmployee { private double x; private double l; public SalesEmployee(String name, int months, int birthday,double x,double l) { super(name, months, birthday); if(super.getMonths()==super.getBirthday()){ System.out.println("员工"+super.getName()+"工资为"+x*l+100); }else{ System.out.println("员工"+super.getName()+"工资为"+x*l); } } }
package week; public class TestCompany { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub ColaEmployee[]y=new ColaEmployee[6]; y[0]=new SalariedEmployee("王", 3, 2, 3000); y[1]=new HourlyEmployee("张", 4, 2, 170, 13); y[2]=new SalariedEmployee("宋", 7, 6, 4000); y[3]=new SalariedEmployee("周", 5, 3, 2000); y[4]=new SalesEmployee("徐", 7, 8, 10000, 0.33); y[5]=new SalesEmployee("陈",8, 7, 20000, 0.43); } }
• 5、利用接口实现动态的创建对象[选做题]
• 5.1 创建4个类:
• 苹果
• 香蕉
• 葡萄
• 园丁
• 5.2 在三种水果的构造方法中打印一句话.
• 以苹果类为例
• class apple
• {
• public apple()
• {
• System.out.println(―创建了一个苹果类的对象‖);
}
• }
课后作业
• 类图如下:
• 5.3 要求从控制台输入一个字符串,根据字符串的
值来判断创建三种水果中哪个类的对象
package week; import java.util.Scanner; interface Fruit { } class Apple implements Fruit { public Apple() { System.out.println("创建了一个苹果对象"); } } class Banana implements Fruit { public Banana() { System.out.println("创建了一个香蕉对象"); } } class Putao implements Fruit { public Putao() { System.out.println("创建了一个葡萄对象"); } } class Gardener { public Fruit create() { Fruit f = null; Scanner input = new Scanner(System.in); String name = input.next(); if (name.equals("苹果")) { f = new Apple(); } else if (name.equals("香蕉")) { f = new Banana(); } else if (name.equals("葡萄")) { f = new Putao(); } else { System.out.println("不会种"); } return f; } }
package week; public class Test { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub Gardener g = new Gardener(); g.create(); } }
