如何从泛型类型获取静态animalType？

import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;

public class Animal<T> {
    private Class<T> animalType;

    public Animal() {
        Type superClass = getClass().getGenericSuperclass();
        if (superClass instanceof ParameterizedType) {
            ParameterizedType parameterizedType = (ParameterizedType) superClass;
            Type[] typeArguments = parameterizedType.getActualTypeArguments();
            if (typeArguments.length > 0) {
                animalType = (Class<T>) typeArguments[0];
            }
        }
    }

    public Class<T> getAnimalType() {
        return animalType;
    }
}

public class Main {
    public static void main(String[] args) {
        Animal<Dog> animal = new Animal<>();
        Class<Dog> animalType = animal.getAnimalType();
        System.out.println(animalType);  // 输出class Dog
    }
}

class Dog {
    // 狗的属性和方法
}
