  2. Establish Connection: Call DriverManager.getConnection(url, username, password) to connect to the database.
  3. Create PreparedStatement: Use Connection.prepareStatement(sql) to create a prepared statement with parameterized queries.
  4. Set Parameters: Use PreparedStatement.setType(index, value) to bind values to query parameters.
  5. Execute Query: Use PreparedStatement.executeQuery() or executeUpdate() to run the parameterized query.
  6. Process Results: For queries, use ResultSet to retrieve and process data.
  7. Close Resources: Call close() on ResultSet, PreparedStatement, and Connection to free resources.
