14-22: Enhance the class-level comment for better documentation.The current class-level comment is not very descriptive. Consider expanding it to provide more information about the purpose and usage of this class, especially since it appears to be a new version.
Here's a suggested improvement:
/** * BillResponseV2 * * This class represents the response structure for bill-related operations in version 2 of the API. * It encapsulates response information and a collection of bills. */municipal-services/ws-calculator/src/main/java/org/egov/wscalculation/web/models/BillV2.java (4)
31-33: Consider adding validation touserIdfieldThe
userIdfield lacks validation annotations. Adding@Size(max = 256)or other appropriate constraints will ensure consistency and data integrity across your model.
50-52: Ensurestatusfield is not nullIf the
statusfield is mandatory for the application's logic, consider adding the@NotNullannotation to enforce this constraint.
64-66: Consider validatingbillDatefieldIf
billDateis a required field, add the@NotNullannotation to ensure it is always provided.
85-87: Add@Validannotation toauditDetailsfieldIncluding the
@Validannotation ensures that the fields withinauditDetailsare also validated according to their constraints.Apply this diff:

Handle invalid inputs in BillStatus.fromValue method

🛠️ Refactor suggestion
Replace magic number with named constant or use TimeUnit for clarity
The code uses a magic number 1296000000l, which reduces readability and maintainability. Consider using TimeUnit.DAYS.toMillis(15) or defining a named constant for better clarity.
Apply this diff to enhance readability:
- billDate = billDate + 1296000000l;
+ billDate = billDate + TimeUnit.DAYS.toMillis(15);Alternatively, define a constant:
+ private static final long FIFTEEN_DAYS_IN_MILLIS = TimeUnit.DAYS.toMillis(15);And update the code:
- billDate = billDate + 1296000000l;
+ billDate = billDate + FIFTEEN_DAYS_IN_MILLIS;| boolean notificationSent = false; | ||

Fix syntax error: invalid statement new ArrayList<>()
The statement new ArrayList<>(); is not valid where it currently appears. It seems like an incomplete variable initialization.
Apply this diff to fix the issue:
- boolean notificationSent = false; new ArrayList<>();
+ boolean notificationSent = false;If you intended to initialize bills, consider initializing it as follows:

| String paymentDueDate = billDateLocal.format(dateTimeFormatter); | ||

Fix potential NullPointerException in null check condition
The condition may throw a NullPointerException if totalAmount is null because totalAmount.signum() is called without a prior null check.

Ensure consistent variable naming for totalAmount
The variable totalamount should be renamed to totalAmount to maintain consistency and adhere to naming conventions.
Apply this diff to fix the variable name:
- if (totalamount != null && totalamount.signum() > 0) {
+ if (totalAmount != null && totalAmount.signum() > 0) {Also, update the method parameter and all usages within the method to use totalAmount.
