    In context to Java programming,

    Is "reference variable of a class" same as "an object of that class"?

    Also for a code like

    class Sample
    {
    int a, b;
    public static void main(String arg[])
    {
    int c;
    // other statements
    }
    }

    Among the variables a,b, c which are the class variables.

    Is there a difference between variable a/b and variable c as far as their scope is concerned?

    I assume you like to know the difference between, Instance variable and local variable.

    There is certainly scope difference between variable "a" and "c".
    "a/b" are class/instance variables .
    "c" is a local variable defined inside the method.
    scope of "a/b" is associated to instance of class, object, just like method, in your program main() method.
    Better go through full tutorial of varial type and do some practice.

    You question is confusing, what exactly you are looking far?
    Are you sure? This action cannot be undone.
