Depending upon the requirement.
Abstract class---->it contains zero or more abstract methods.
ex HttpServlet and GenericServlet
HttpServlet contains all sre concrete methods but it
declared as a Abstract class.
InterFace--->It contains all abstract methods.
if we extends the abstract class .there is chance to extend
another class.
if we implements the interface we can extends another class
