This search algorithm works on the principle of divide and conquer. For this algorithm to work properly, the data collection should be in the sorted form. Binary search looks for a particular item by comparing the middle most item of the collection. WebIn Java, binarySearch () is a method that helps in searching a particular key element from several elements using the binary search algorithm. In order to perform this operation, elements have to be sorted in ascending order. If it is not sorted, it can be sorted using the method Arrays.sort (arr). Otherwise, results are said to be undefined. can birds fly when wet
