JAVA报错No enclosing instance of type Test is accessible...

最近学习java抽象类和接口，运行书上的例题，出现报错，
No enclosing instance of type Test is accessible. Must qualify the allocation with an enclosing instance of type Test (e.g. x.new A() where x is an instance of Test).

接口：
public interface Edible {
public abstract String howToEat();
}

测试类：

public class Test {

public static void main(String[] args) {
// TODO Auto-generated method stub
Object[]object={new Tiger(),new Chicken(),new Apple(),new Orange()};

}
class Animal{

}
class Chicken extends Animal implements Edible{
public String howToEat(){
return "Chicken:Fry it";
}
}
class Tiger extends Animal{
public String howToEat(){
return "Chicken:Fry it";
}
}

abstract class Fruit implements Edible{}

class Apple extends Fruit{
public String howToEat(){
return "Apple:Make apple cider";
}
}
class Orange extends Fruit{
public String howToEat(){
return "Orange:Make orange juice";
}
}

}

你这写的都是内部类吗?如果不是内部类就不会有问题的

在内部类创建对象的时候要求创建外部类的对象。静态方法中不能直接调用非静态方法，必须通过创建对象来调用。
把Test类中的main()方法中改成:

    Object[]object={new Test().new Tiger(),new Test().new Chicken(),new Test().new Apple(),new Test().new Orange()};

也可以把new Test()提出来

    Test test = new Test();
    Object[]object={test.new Tiger(), test.new Chicken(), test.new Apple(), test.new Orange()};
