Factory Pattern

Analogy: pattern

The Factory Pattern is like ordering from a Menu.

You say "I want a Burger". You don't go into the kitchen, chop the onions, and grill the patty yourself (new Burger()).

The Factory (Kitchen) handles the creation logic and hands you the finished object.

The Toy Factory

Order a toy from the factory.

You don't need to know how to build a Car or a Doll.
You just ask the Factory for one.

        if (type.equals("Car")) return new Car();
        else if (type.equals("Doll")) return new Doll();
        return null;
    }
}

// Usage
ToyFactory factory = new ToyFactory();
Toy myToy = factory.createToy("Car");
