Java Program for Binary Search on Java float Array

       public class BinarySearchFloatArrayExample
   {
     public static void main(String[] args)
     {
       //create float array
       float floatArray[] = {1.23f,2.10f,4.74f,5.34f};
      
       /*
       To perform binary search on float array use
       int binarySearch(float[] b, float value) of Arrays class. This method searches
       the float array for specified float value using binary search algorithm.
      
       Please note that the float array MUST BE SORTED before it can be searched
       using binarySearch method.
      
       This method returns the index of the value to be searched, if found in the
       array.
       Otherwise it returns (- (X) - 1)
       where X is the index where the the search value would be inserted.
       i.e. index of first element that is grater than the search value
       or array.length, if all elements of an array are less than the
       search value.

       //sort float array using Arrays.sort method
       Arrays.sort(floatArray);
      
       //value to search
       float searchValue = 4.74f;
      
       //since 4.74 is present in float array, index of it would be returned
       int intResult = Arrays.binarySearch(floatArray,searchValue);
       System.out.println("Result of binary search of 4.74 is : " + intResult);
      
       //lets search something which is not in float array !
       searchValue = 3.33f;
       intResult = Arrays.binarySearch(floatArray,searchValue);
       System.out.println("Result of binary search of 3.33 is : " + intResult);
