   Java Sort double Array Example
   This example shows how to sort a double array using sort method of Arrays class of
   java.util package.

     To sort java double array use Arrays.sort() method of java.util package.
     Sort method sorts double array in ascending order and based on quicksort
     algorithm.
     There are two static sort methods available in java.util.Arrays class
     to sort a double array.

      inclusive and endIndex is exclusive

/*
Output Would be

Original Array :     3.0  2.0  5.0  4.0  1.0
Sorted double array :     1.0  2.0  3.0  4.0  5.0
Partially Sorted double array :     5.0  1.0  2.0  3.0  4.0
