Pagination in Servlet

To divide large number of records into multiple parts, we use pagination. It allows user to display a part of records only. Loading all records in a single page may take time, so it is always recommended to created pagination. In servlet, we can develop pagination example easily.

In this servlet pagination example, we are using MySQL database to fetch records.

Here, we have created "emp" table in "test" database. The emp table has three fields: id, name and salary. Either create table and insert records manually or import our sql file.
