How do you define the Super keyword?
It is a keyword using which we can point to the immediate super object of the current object. The Super keyword cannot be used in the static blocks.
This is because the super keyword points to the immediate superclass object of the current object and we know that static blocks will not work in objects.
What are the uses of the keyword super
a) We can refer to the properties of the immediate superclass object from the subclass object?
b) We can explicitly call immediate superclass constructors from the subclass constructors.
Whenever a class extends another class, always the superclass constructors are executed first.
In every constructor, we have a default statement. The default statement is nothing but super (). As soon as the control enters the constructor of a class whether that class is extending any other class or not.
If the statement is yes, it creates an object of the superclass by executing the super (); statement in the current constructor. This is the reason why superclass constructors are executed first.
