1// Java code is not applicable for database queries.Java can execute SQL commands via JDBC, but constructing the exact queries should be done in SQL within the database context.
This approach involves extracting trip data and user data, performing filtering operations in the application logic to compute stats, and then using aggregation to calculate the cancellation rate for each day.
