The ques is
interface I {String s1 = "I";}
class A implements I {String s1 = "A";}
class B extends A {String s1 = "B";}
class C extends B {
String s1 = "C";
void printIt() {
System.out.print(((A)this).s1 + ((B)this).s1 +
((C)this).s1 + ((I)this).s1);
}
public static void main (String[] args) {
new C().printIt();
}}
The ans is ABCI.
I am a bit lost in the SOP line in the class C. How should I interpret this type cast?
Please advice.
