Java Database Connectivity (JDBC) is an API (Application Programming Interface) in Java that defines how a client may access a database. It provides methods to query and update data in a database, and it is part of the Java Standard Edition platform.

Key Concepts of JDBC
JDBC Driver: A JDBC driver is a set of classes that implement the JDBC interfaces for communicating with a specific database. There are four types of JDBC drivers:

Type 1: JDBC-ODBC bridge driver
Type 2: Native-API driver
Type 3: Network Protocol driver
Type 4: Thin driver (pure Java driver)
Connection: This interface establishes a connection to the database. It contains methods for creating statements, committing transactions, and closing the connection.

Statement: An interface used for executing a static SQL statement and returning the results it produces. The main types are:

Statement: Used for general-purpose access to the database.
PreparedStatement: Used for executing precompiled SQL queries with parameterized inputs, offering performance benefits and protection against SQL injection.
CallableStatement: Used to execute stored procedures in a database.
ResultSet: This interface represents the result set of a query. It allows the retrieval of data returned by the SELECT statement in a tabular form.

DriverManager: This class manages a list of database drivers. It loads the database driver, establishes a connection, and helps in selecting the appropriate driver for a specific database.

Basic Steps to Connect to a Database using JDBC
Load the JDBC Driver: Depending on the database you are connecting to, you need to load the corresponding JDBC driver
