Hi Friend,

Comparator interface is used to sort a collection by custom sorting.
To sort the data elements a class needs to implement Comparator or Comparable interface.

For more information, visit the following links:

/tutorial/java/io/sortFileData.html

To access the element of a collections, there are two ways:

1.Use get(index) method of Collection object to get the element of the object.This method will return Object only.
2.Use Enumeration or Iterator object to get the object one by one.

Thanks
