Answer / priyanka das

"super" is a keyword used to invoke superclass data members and also superclass member methods,whereas "this" is a keyword used to invoke the current class data member as well as current class member methods.

A super object can be used to retrieve super class members."this' object can be used to invoke only the current class members.

1) It points to current class object
2) It whenever formal parameters of the class are similar then jvm gets an ambiguity.
"super" is a keyword which will differentiate base class features with derived class features.
