I have an example.
class Candidate
is superclass and ExperienceCandidate
is subclass.
i have 2 type to create object is:
ExperienceCandidate temp = new ExperienceCandidate();
Candidate temp = new ExperienceCandidate();
Help me distinguish the differences between these two constructs and which one is used in which case
Generally whenever you are creating an object , it is just to create an instance of the class so that you can use it somewhere. In the case of Superclasses and Subclasses , whenever you initiaze a subclass of a class , it already contains all the objects/methods of the superclass. In your case , there are two logical discrepancies :
Candidate temp = new ExperienceCandidate();
is not the correct way to call an object , the correct way to call the object of the superclass is Candidate temp = new Candidate();
super()
to call the constuctor of the superclass and anyway all the function of the superclass are available for you to use in the subclass (since you extended to it)
