个ColaEmployee 数组里，并单元出数组中每个员工当月的
工资。

 • 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 Work;

public interface Fruit {

}

class Apple implements Fruit {
    public Apple() {
        System.out.println("创建了一个苹果类的对象");
    }

}

class Banana implements Fruit {
    public Banana() {
        System.out.println("创建了一个香蕉类的对象");
    }
}

class Grape implements Fruit {
    public Grape() {
        System.out.println("创建了一个葡萄类的对象");
    }
}

package Work;

import java.util.Scanner;

public class Gardener {

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

    }

    public Fruit create() {
        Scanner input = new Scanner(System.in);
        String name = input.next();

        Fruit f = null;
        if (name.equals("苹果")) {
            f = new Apple();
        }
        if (name.equals("香蕉")) {
            f = new Banana();
        }
        if (name.equals("葡萄")) {
            f = new Grape();
        }
        return f;
    }
}
