Java第十五次作业

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。

课后作业
• 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

import java.util.Scanner;
public interface shuiguo {

}
class Apple implements shuiguo {
    public Apple() {
        System.out.println("创建了一个苹果对象");
    }
}

class Banana implements shuiguo {
    public Banana() {
        System.out.println("创建了一个香蕉对象");
    }
}

class Grape implements shuiguo {
    public Grape() {
        System.out.println("创建了一个葡萄对象");
    }
}

class Gardener {
    public shuiguo create() {
         System.out.println("请输入水果名称");
        shuiguo 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 Grape();
        } else {
            System.out.println("no");
        }
        return f;

    }
}
public class testshuigou {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Gardener g = new Gardener();
        g.create();
    }

}
