Access class variable using Interface type

Question

I\'ve following class

class MyClass implements Intrfc {

String pickmeUp = \"Its Me\";

public static void main(String[] args){

Intrfc ob = new MyClass();
ob.pi         


        

Answer 1

In this definition:

class MyClass implements Intrfc {
    String pickmeUp = "Its Me";
}

the field pickmeUp is not even a member of Intrfc interface, so there is no possibility to reach for it using just the interface. pickmeUp is a member of a concrete class - MyClass.
