| Ans. Inner Class is a class that is nested within another class whereas sub class is a class that extends or inherit another class. Inner class can only be accessed using reference of outer class ( Class name , if inner class is static or object reference, if inner class is non static ) whereas Sub class is accessed directly. In terms of memory, inner class is stored just like another class having it's own body whereas sub class carries the body of parent class as well as it's own fields in memory. | |||||
