Answer / ganesh
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..

Answer / krish
Inheritance:Your are in a situation where you have to the
properties of a whole class repeatedly then you can go for
inheritance.
Note:Final class can't be inherited.
Polymorphism:When you are in a situation where you need to
use a method repeatedly then you can go for polymorphism.
Eg:
consider this method
add(int i,int j) and add(String s1,String s2)
the former will add two integers and later will concatenate
two strings but both using the same method name.

Answer / kishor kommulas
Inheritance:::
If you want to make use of the functionality of the method,
which is already there then you can go for the inheritance.
Polymorphism::::
If you want to use the same method name for different
method,then you can go for Polymorphism.
