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.
