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.
Again super() can be used to invoke the superclass constructor where as this() can be used to invoke current class constructor.

Answer / shanthappa
"this" is the implicit keyword/object oriented by the jvm and supplied to every java programs for two purposes.
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.
The keyword 'super' is placing an important role in three places in java...
1)at variable level
2)at constructor level
3)at method level
