Answer:
Addresses.
Explanation:
An argument can be defined as a value that can be passed to a function.
Simply stated, an argument is a value that must be passed into a function, subroutine or procedure when it is called. This value can be passed to a function either by reference or by value.
This ultimately implies that, an argument which is also a parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
When calling a function with arguments that should be modified, the addresses of those arguments are passed. This is simply because the argument is an address or pointer in itself and as such the function parameter being called must be a pointer.
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Hence, all instance variables that have been used or declared in any superclass would be present in its subclass object.
