JAVA CODE NEEDED THANK YOU. i have 1hour and 3minutes from now.

A bill is characterized by number(unique), date, sum, issuer. In main method add 3 bills to a LinkedList, then add them to a HashSet (duplicate bills should be removed automatically) then add them to a TreeSet. Implement class Bill (with all required methods!) and main method.

Implement a BillRepository class that manages a collection of bills. Class should have methods for adding new bills, getting a bill (or a bill collection) by number, date, sum or issuer. Implement a method that returns a bill/ bill collection based on more than one field. Also implement BillRepositoryI interface that exposes the methods in BillRepository.

Implement a Company thread that continuously adds bills in an AuditReport and an Auditor thread that continuously removes bills from the AuditReport and outputs randomly if the current bill is correct or not. Use producer-consumer pattern with wait/notify. Do not use explicit locks or blocking queues or other concurrent collections.
