Binary search is faster then linear search if the collection is sorted and does not contains duplicated Values

public static void BinarySearch(int searchVal)
{
  int lowerIndex = 0;
  int higherIndex = arrNumbers.length;
  int searchIndex = 0;
  
  while(lowerIndex < higherIndex)
  {
	int middleIndex = (lowerIndex + higherIndex)/2;
	
	if(searchVal < arrNumbers[middleIndex])
	{
		higherIndex = middleIndex + 1; 
	}
	else if(searchVal > arrNumbers[middleIndex])
	{
		lowerIndex = middleIndex - 1;
	}  
	else
	{
		searchIndex = middleIndex+1;			
		System.out.println("The element is Found at Index " + searchIndex);
		return;
	}
  }
}
