java instanceof()问题求解

public class FruitTest {
public static void main(String[] args) {
Fruit fruit = new GoldenDelicious();

Orange orange = new Orange();
    //Orange p = new Apple();
    //Macintosh p = new Apple();
    //Apple p = new Macintosh();

    System.out.println(fruit instanceof Orange);
    System.out.println(fruit instanceof Apple);
    System.out.println(fruit instanceof GoldenDelicious);
    System.out.println(fruit instanceof Macintosh);
    System.out.println(fruit instanceof Orange);
    System.out.println(orange instanceof Fruit);
    System.out.println(orange instanceof Apple); //这一句一直是说有问题不匹配（难道不可以输出false吗），但是如果我注释掉，前面ruit fruit = new GoldenDelicious();就报错，但是跟这一句没关系吧，这一句是自动向上转型吗？? 谢谢指导。


}

class GoldenDelicious extends Apple{
    public GoldenDelicious(){}
}
class Macintosh extends Apple{
    public Macintosh(){}
}
class Apple extends Fruit{
    public Apple(){}
//  public void makeAppleCider(){}
}
class Orange extends Fruit{
    public Orange(){}
    //public void makeAppleCider(){}
}
class Fruit{
    public Fruit(){}
}
}
