Hello OOP Experts and Design Pattern Experts,
In one of my project, I have to implement Factory design pattern to solve a specific issue.
I have one parent interface and two child interfaces. In next stage, I have to create a factory which will return an instance of a specific class based on given input. Please see below SAMPLE code which is easy to understand my problem and sample image as well.
Sample Diagram
Sample Code
enum AnimalType{ DOG, CAT }
Class Factory{
public Animal getInstance(AnimalType animalType){
Animal animal = null;
switch(animalType){
case DOG: animal = new Dog();
break;
case CAT: animal = new Cat();
break;
default:
break;
}
return animal;
}
}
/*Actual Problem */
Animal animal = Factory.getInstance(AnimalType.DOG);
/* When I use any IDE like IntellijIdea or Eclipse it only provides eat() method after animal and dot (ie. animal. ) */
animal.<SHOULD PROVIDE eat() and woof() from Dog> but it is only providing eat()
