What is JDBC and what are its main components?
Java Database Connectivity is an API for connecting Java applications to relational databases. Key components: DriverManager (obtains connections), Connection (session with the DB), Statement/PreparedStatement (executes SQL), and ResultSet (holds query results).
Example
Connection conn = DriverManager.getConnection(url, user, pass);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM users");
