简单工厂模式拿不到实例？

Question

package site.yanhui.section4;

public interface Fruit {
      public void get();
}

package site.yanhui.section4;

public class Banana implements Fruit {

    @Override
    public void get() {
        System.out.println("采集香蕉");
    }
}

package site.yanhui.section4;


public class FruitFactory {

    /**
     * 获得所有的产品对象
     *
     */

    public  static Fruit getFruit(String type) throws IllegalAccessException, InstantiationException, ClassNotFoundException {

       Class fruit = Class.forName(type);


       return (Fruit) fruit.newInstance();


    }
}

package site.yanhui.section4;

public class MainClass {

    public static void main(String[] args) throws InstantiationException, IllegalAccessException, ClassNotFoundException {

//           Fruit apple = FruitFactory.getFruit("Apple");

        Fruit banana = FruitFactory.getFruit("Banana");
        banana.get();

明明有香蕉类，但是为什么一直报错说没有找到类呢？

Answer 1

输入完整包名+类名试试

Answer 2

为了避免同名类的问题，要精准到包+类，Class.forName(xxx.xx.xx)
