Java program for Binary search using Iterative Approach

By | June 1, 2020

Hello Friends,
In this post,we will talk and learn about How to Write a Java program for binary search using the Iterative Approach?

Binary search is one of the search techniques. Which works efficiently on the sorted arrays or collection. Hence, in order to search an element in array or collection by using binary search techniques, we must ensure that the array or collection is sorted.

The binary search uses a divide and conquer algorithm in which, the arrays or collection is divided into two halves and the item is compared with the middle element of the collection. If the match is found for a given searching key then the location of the middle element is returned. Otherwise, we have to search into either of the halves depending upon the result produced through the match.

 Few Sample input/output of the above program: 

Enter input Array Size:
6
Enter 6 Array Elements:
12
78
20
19
27
85
input Array::
[12, 19, 20, 27, 78, 85]
Enter Seach Key Element:
27
27 found at index: 3


Enter input Array Size:
5
Enter 5 Array Elements:
12
45
61
13
14
input Array::
[12, 13, 14, 45, 61]
Enter Seach Key Element:
123
