Inheritance :
If you want to reuse the existing class
characteristics(methods,variables ..) then you will use
inheritance ..
Polymorphism :
If you want a method to respond based on our requirement
then we will use polymorphism ..for example like swapping
two variables is same for all types but if write program
means for different types(int,double,char..) u need to write
different methods but under a common method name..
