1.Enumeration interface applicable legacy implemented classes.
Iterator is applicable for all collection implemented classes.
2.Enumeration :While iterating the elements we are not
allowed to remove the objects just we can perform only read
operation
Iterator:While iterating we can perform removal also in
addition to read operation
3. Enumeration uses elements() method ,
Iterator uses iterator() method
