How to implement Linear Search in Java? Example tutorial

In the last article about searching and sorting, we have learned binary search algorithm and today I'll teach you another fundamental searching algorithm called Linear search. Linear search is nothing but iterating over the array and comparing each element with target element to see if they are equal since we search the array sequential from start to end, this is also known as sequential search or linear search. It is very slow as compared to binary search because you have to compare each element with every other element and definitely not suitable for a large array. It's practically useful only in case of the small array up to 10 to 15 numbers. In the worst case, you need to check all elements to confirm if target element exists in an array or not.
