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.
