There are two types of Streams and they are: Byte Streams: Provide a convenient means for handling input and output of bytes.
Statement.execute Update() method returns you number of records got updated.
A Stream is an abstraction that either produces or consumes information.

= /* means that all requests of users have go through this filter.
User Account; public class DBUtils In JDBCFilter, I checked which requests actually referred to a Servlet, so that you can see the picture below to find it easy to understand, it describes the relationship between the concepts of Servlet.
This example shows how to update table records using SQL update query.
By using Statement.execute Update() you can execute update statements.
If we did a forward, then after the form submission the browser would show the listing, but under the URI /book instead of /book/.
If the ender user linked to /book, it would not take them back to the listing but back to a form, which not correct. We have created the following files for this bookstore example: $ find . ./Web Content/WEB-INF/pages/Book Form ./Web Content/WEB-INF/pages/Book Listing ./src/META-INF/Needed for Java EE dependency injection (CDI) ./src/com/bookstore/Domain/model object ./src/com/bookstore/Book Repository Repository implementation using Java collections (just for testing) ./src/com/bookstore/Book Interface to Book Repository so we can swap it out with JDBC, JPA, JCache and Mongo DB version later ./src/com/bookstore/web/Book Editor Servlet that loads Book (do Get) form and handles Book form submissions (do Post).
