Toy Factory

Problem

Factory is a design pattern in common usage. Please implement a ToyFactory which can generate proper toy based on the given type.

ToyFactory tf = ToyFactory();
Toy toy = tf.getToy('Dog');
toy.talk();
>> Wow

toy = tf.getToy('Cat');
toy.talk();
>> Meow

Code - Java

/**
 * Your object will be instantiated and called as such:
 * ToyFactory tf = new ToyFactory();
 * Toy toy = tf.getToy(type);
 * toy.talk();
 */
interface Toy {
    void talk();
}

class Dog implements Toy {
    // Write your code here
    @Override
    public void talk() {
        System.out.println("Wow");
    }
}

class Cat implements Toy {
    // Write your code here
    @Override
    public void talk() {
        System.out.println("Meow");
    }
}

public class ToyFactory {
    /**
     * @param type a string
     * @return Get object of the type
     */
    public Toy getToy(String type) {
        // Write your code here
        if (type.equals("Dog")) {
            return new Dog();
        } else if (type.equals("Cat")) {
            return new Cat();
        } else {
            return null;
        }
    }
}
