   Java Sort float Array Example

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

     to sort a float array.

Output Would be
 
Original Array :     3.0  2.0  5.0  4.0  1.0
Sorted float array :     1.0  2.0  3.0  4.0  5.0
Partially Sorted float array :     5.0  1.0  2.0  3.0  4.0
