? 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。
public class ColaEmployee {
String name;
int month;
public ColaEmployee(String name, int month) {
super();
this.name = name;
this.month = month;
}
public ColaEmployee() {
}
public double getSalary(int month) {
return 0;
}
}
public class Company {
public void getSalary(ColaEmployee c,int month) {
System.out.println(c.name + "在" + month + "月的月薪为" + c.getSalary(month)+"元");
}
}
public class HourlyEmployee extends ColaEmployee{
private int hourSalary;
private int hourNum;
public HourlyEmployee(String name, int month,int hourSalary,int hourNum) {
super(name,month);
this.hourSalary=hourSalary;
this.hourNum=hourNum;
}
public double getSalary(int month) {
if(super.month==month) {
if (hourNum>160) {
return hourSalary*160+hourSalary*(hourNum-160)*1.5+100;
}else {
return hourSalary*hourNum+100;
}
}else {
if (hourNum>160) {
return hourSalary*160+hourSalary*(hourNum-160)*1.5;
}else {
return hourSalary*hourNum;
}
}
}
}
public class SalariedEmployee extends ColaEmployee {
double monSalary;
public SalariedEmployee(String name,int month,double monSalary) {
super(name,month);
this.monSalary=monSalary;
}
public double getSalary(int month) {
if (super.month==month) {
return monSalary +100;
}else {
return monSalary;
}
}
}
public class SalesEmployee extends ColaEmployee{
private int monthSales;
private double royaltyRate;
public SalesEmployee(String name, int month,int monthSales,double royaltyRate) {
super(name, month);
this.monthSales = monthSales;
this.royaltyRate = royaltyRate;
}
public double getSalary(int month) {
if(super.month == month) {
return monthSales * royaltyRate + 100;
}else {
return monthSales * royaltyRate;
}
}
}
public class text {
public static void main(String[] args) {
ColaEmployee[] a = {
new SalariedEmployee("salariedEmployee", 4, 15000),
new HourlyEmployee("hourlyEmployee", 5, 15, 756),
new SalesEmployee("salesEmployee", 7, 46562, 0.3)
};
for (int b = 0; b < a.length; b++) {
new Company().getSalary(a[b],6);
}
}
}
? 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
public interface jiekou{
}
public class pingguo implements jiekou{
public pingguo()
{
System.out.println("一个苹果对象");
}
}
public class putao implements jiekou{
public putao()
{
System.out.println("一个葡萄对象");
}
}
public class xiangjiao implements jiekou{
public xiangjiao()
{
System.out.println("创建了一个香蕉对象");
}
}
import java.util.Scanner;
public class yuanding {
public jiekou create() {
Scanner input = new Scanner(System.in);
jiekou jiekou = null;
String name = input.next();
if (name.equals("苹果")) {
jiekou = new pingguo();
} else if (name.equals("香蕉")) {
jiekou = new xiangjiao();
} else if (name.equals("葡萄")) {
jiekou = new putao();
} else {
System.out.println("不会种");
}
return jiekou;
}
}
public class text {
public static void main(String[] args) {
yuanding g = new yuanding();
g.create();
}
}
