/**

* 7-4

* Write a exercise class that contains the following methods

* 1> Statistics (Object arc[]) method:

* Count the number of occurrences of each letter (regardless of case) relative to the total number of letters,

* Print Show this ratio

* 2> Sort (Object arc[]) method:

* Sort the given array.

* Programmatically create an object of the exercise class,

* Receive user input from the main method in English text,

* and deposit it into the newly created object.

* Display the output result by calling the object method.
