Write a program in Java to demonstrate reflection. 
import java.lang.Class;
import java.lang.reflect.*;

class Animal {
}

public class Dog extends Animal {
    public void display() {
        System.out.println("I am a dog.");
    }
}

class Main {
    public static void main(String[] args) {
        try {
            Dog d1 = new Dog();
            
            Class obj = d1.getClass();

            String name = obj.getName();
            System.out.println("Name: " + name);

            int modifier = obj.getModifiers();

            String mod = Modifier.toString(modifier);
            System.out.println("Modifier: " + mod);

            Class superClass = obj.getSuperclass();
            System.out.println("Superclass: " + superClass.getName());
        }

        catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Output
Name: Dog
Modifier: public
Superclass: Animal
