postgresqlHow do I use the PostgreSQL JDBC driver?

The PostgreSQL JDBC driver is a Java library used to connect to a PostgreSQL database. To use it, you must include the driver jar in your classpath and then use the JDBC API to create a connection.

Example code

// Load the PostgreSQL JDBC driver
Class.forName("org.postgresql.Driver");

// Establish a connection
String url = "jdbc:postgresql://localhost:5432/dbname";
String username = "username";
String password = "password";
Connection conn = DriverManager.getConnection(url, username, password);

The code above:

1. Loads the PostgreSQL JDBC driver class org.postgresql.Driver.
2. Establishes a connection to a PostgreSQL database using the DriverManager.getConnection() method. This method takes the database URL, username, and password as parameters.
