f564fa4ea1 Added the counting sort method which uses stream API 
Changed the original sorting method: creating and throwing an exception it costs then using getOrDefault for a map

CombSort.java 
Comb Sort is mainly an improvement over Bubble Sort. Bubble sort always compares adjacent values. So all inversions are removed one by one. Comb Sort improves on Bubble Sort by using gap of size more than 1. The gap starts with a large value and shrinks by a factor of 1.3 in every iteration until it reaches the value 1. Thus Comb Sort removes more than one inversion counts with one swap and performs better than Bubble Sort.

The shrink factor has been empirically found to be 1.3 (by testing CombSort on over 200,000 random lists) [Source: Wiki]

Although, it works better than Bubble Sort on average, worst case remains O(n2).

Removing unused imports, cleaning up (at a base level) code, and removing some package declarations. By no means did I get all of them.

e5dd6eff02 Updated to more efficient version if array size is scaled. 
Changed loop from "for" to "do-while". Added decrement at end of do loop to decrease size of array tested after each iteration.
