/* Description:

* 1. Complete the Box file

* a. Complete the constructors

* b. Write down the set and get methods for variables

* 2. Read the boxfile.txt using scanner

* -. First line of the file contains how many boxes are there

* -. Following N rows contains length, width, height of each boxes

* 3. Create Box class Array

* 4. Store all the rows in the Box class array using get set method or Constructor

*

* 5. Find the box with maximum length

* 6. Find the box with minimum length

* 7. Compute volume of each boxes and print that

* 8. Find the box with max volume

* 9. Find the box with min volume
