Definitely. That is actually the prefer way to make your client code more flexible and easier to maintain.For example, in a gaming program, you have:Breakable b = Factory.createObject();b.performBreak();It doesn't matter what concret Obejct Factory.createObect() returns, as long as it implements performBreak() method. The object return could be a character object, background object, automobile object.
