Java Search Algorithms

Search algorithm is an algorithm for finding an item with specified properties among a collection of items. The items may be stored individually as records in a database or may be elements of a search space defined by a mathematical formula or procedure, such as the roots of an equation with integer variables or a combination of the two.

You can find examples for different types of search algorithms here.

Java Search Algorithms Examples

  1. Write a program to implement Linear search or Sequential search algorithm.
  2. Implement Binary search in java using divide and conquer technique.
  3. Implement Binary search in java using recursive algorithm.

When to use LinkedList or ArrayList?
Accessing elements are faster with ArrayList, because it is index based. But accessing is difficult with LinkedList. It is slow access. This is to access any element, you need to navigate through the elements one by one. But insertion and deletion is much faster with LinkedList, because if you know the node, just change the pointers before or after nodes. Insertion and deletion is slow with ArrayList, this is because, during these operations ArrayList need to adjust the indexes according to deletion or insetion if you are performing on middle indexes. Means, an ArrayList having 10 elements, if you are inserting at index 5, then you need to shift the indexes above 5 to one more.
