   Java Sort double Array Example

     To sort java double array use Arrays.sort() method of java.util package.

     to sort a double array.

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
