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…
- Java Code: Create a Parser class. Much like the Lexer, it has a constructor that accepts a LinkedList of Token and creates a TokenManager that is a private member. The next thing that we will build is a helper method – boolean AcceptSeperators(). One thing that is always tricky in parsing languages is that people can put empty lines anywhere they want in their code. Since the parser expects specific tokens in specific places, it happens frequently that we want to say, “there HAS to be a “;” or a new line, but there can be more than one”. That’s what this function does – it accepts any number of separators (newline or semi-colon) and returns true if it finds at least one. Create a Parse method that returns a ProgramNode. While there are more tokens in the TokenManager, it should loop calling two other methods – ParseFunction() and ParseAction(). If neither one is true, it should throw an exception. bool ParseFunction(ProgramNode) bool ParseAction(ProgramNode) -Creates ProgramNode,…Help with this java question: Map<KeyType, ValueType> mapName = new HashMap<>();in java please.Create a method from the implementation perspective.

- Make a distinction between the Java classes GenericServlet and HttpServlet using an example.Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method score() of the parent class to calculate the weighted score for both types of students. Write a driver class JavaProgramming.java which has the main method. Create one remote student object and one in-person student object. The output should show prompts to enter individual scores – midterm, finals, ...... etc. and the program will…It is unclear how many nodes are included in the strongest linkedlist currently available.Is there one in particular that sticks out as being very protracted?

Assume that the linkedlist has an even number of nodes >2 and only two of the nodes has a duplicate value. Write a Java method called swapDuplictes that swaps the first duplicate with the node before the last node in the linkedlist and swaps the second duplicate with the last node in the linked list. Note: You are not allowed to exchange values of nodes or use any of the add, insert, or remove methods from MyLinkedList class. You have to perform the task by moving the next link. consider the following example of a linkedlist containing six nodes: Before calling the method head tail After calling the method head tail
