Integration with calculation layer

Calculation - The calculation class will contain the calculation logic for given service delivery. Based on the application submitted the calculator class will calculate the tax/charges and call billing service to generate demand.

For our guide, we are going to create a sample calculation class with some dummy logic. For this, we are going to perform the following steps -

i) Create a class under service folder by the name of CalculationService

ii) Now, annotate this class with @Service annotation and add the following logic within it -

@Service
public class CalculationService {
    public Double calculateLaminationCharges(VoterRegistrationApplication application){
        // Add calculation logic according to business requirement
        return 10.0;
    }
}
