Statement , interface is used to execute SQL statements against a relational database. You obtain a JDBC Statement from a JDBC Connection. Once you have a Java Statement instance you can execute either a database query or an database update with it.
Likewise, how do I connect to JDBC? The steps for connecting to a database with JDBC are as follows:
- Install or locate the database you want to access.
- Include the JDBC library.
- Ensure the JDBC driver you need is on your classpath.
- Use the JDBC library to obtain a connection to the database.
- Use the connection to issue SQL commands.

- PreparedStatement: It can be used when you plan to use the same SQL statement many times.
- CallableStatement: CallableStatement can be used when you want to access database stored procedures.
Why do we use PreparedStatement?
Benefits of Prepared Statement: It can be used to execute dynamic and parametrized SQL Query. PreparedStatement is faster then Statement interface. Because in Statement Query will be compiled and execute every times,while in case of Prepared Statement Query won't be compiled every time just executed.What is difference between statement and PreparedStatement in JDBC?

How does Jdbc work?
The JDBC Driver is a set of classes that implement the JDBC interfaces to process JDBC calls and return result sets to a Java application. The database (or data store) stores the data retrieved by the application using the JDBC Driver. A Connection object controls the connection to the database.Is connection a class or interface?
