Below shape is an interface and circle and triangle are implementation
Likewise  color is an interface and it's implementations

AbstractFactory is class which will create an instance of class depending data passed by user

For example

If (name.equals("circle"))
      new Circle();

Q)I was asked in an interview can you create object using reflection here instead of hard coding?

And)Class .forename(circle).new instance();

He was not satisfied.

Please correct my answer if it was wrong?


AbstractFactory
Shape get shape(String name)
Colour get colour(String name)


Shape factory                   ColourFactory  abstract

Shape (I)                                color (I)
 Circle    Triangle                   Red Green

I'm pretty sure the interviewer intended for you to use one of the factories.
 
You know it is dark times when the trees riot. I think this tiny ad is their leader:
