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
package Week15;
import java.util.Scanner;
public 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;
}
}
public class textfruit {
public static void main(String[] args) {
Gardener g = new Gardener();
g.create();
}
}
