VariableReferenceNode.java, OperationNode.java, ConstantNode.java, and PatternNode.java must have their own java classes with the correct methods implemented:  OperationNode: Has enum, left and Optional right members, good constructors and ToString is good  VariableReferenceNode: Has name and Optional index, good constructors and ToString is good  Constant & Node Pattern: Have name, good constructor and ToString is good    Make sure to include the screenshot of the output of Parser.java as well.

Java Code: Build the two variable classes that we need: InterpreterDataType and a subclass InterpreterArrayDataType. I will abbreviate these as IDT and IADT. IDT holds a string and has two constructors - one with and one without an initial value supplied. IADT holds a HashMap<String,IDT>. Its constructor should create that hash map. We will use these as our variable storage classes as the interpreter runs. Let's start the interpreter itself. Create a new class (Interpreter). Inside of it, we will have an inner class - LineManager. We will also need a HashMap<String,IDT> that will hold our global variables. We will also have a member HashMap<String, FunctionDefinitionNode> - this will be our source when someone calls a function. The LineManager should take a List<String> as a parameter to the constructor and store it in a member. This will be our read-in input file. It will need a method : SplitAndAssign. This method will get the next line and split it by looking…

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…

In Java, Create Movie class, which has private fields for title, director, rating. It has a constructor to initialize these fields and a toString method for printing movie details. There is also a getRating method to retrieve the movie rating. Create Rating Comparator class which implements the Comparator interface for comparing movies based on their ratings. Create DemoMovies Class. Initialize necessary data structures like LinkedList, TreeMap for rating as key and Movie from Movie class as value, TreeSet, and ProtiyQueue. Use a loop to take user input for movie detailsuntil the user enters 'WWW' as the movie title.Inside the loop, for each movie, create a Movie object, add it to various data structures that is title, director and rating based on the constructor. Add the Movie object to the LinkedList. Add the rating and the object to the TreeMap.Add the rating to the TreeSet.Add the Movie object to the Priority Queue.Display the entered movies. Sort and display Movies by rate by…

Code with java please.   Critique the following code which is intended to print out whether or not a key value k1 is used in a map named relationships:   if (relationships.get(k1) != null) System.out.println("yes it does"); else System.out.println("no it does not");   Now rewrite the code so that it works correctly.

1. Show the ListStackADT<T> interface 2. Create a ListStackDataStrucClass<T> with the following methods: defaultconstructor, overloaded constructor, copy constructor, getTop, setTop,isEmpty, ifEmpty (if empty throw the exception), push, peek, pop, toString. 3. Create a private inner class of ListStack<T> called StackNode<T> with thefollowing methods: default constructor, overloaded constructor, copyconstructor, getValue, getNext, setValue, setNext 4. Create a BaseConverter class (non-generic) with the following methods: defaultconstructor, inputPrompt, convert [converts a BaseNumber to a convertedString], convertAll [instantiate a String object] , toString, processAndPrint     5. Create a private inner class BaseNumber. The inner class has the following methods: default constructor, overloaded constructor, getNumber, getBase,setNumber, setBase. [Make your private instance variables in the inner classLong type]. 6. Create a BaseConverterDemo class that only…

Through java, have The Delicious class – fields and constructor The class must define and initialise a field of an appropriate collection class to store Chicken objects. There must be no pre-defined limit on the number of Chiciken objects it can store.The Delicious class – basic methodsThe Delicious class must:• Define a method called addChicken that takes a Chicken object as a parameter and adds it to the ArrayList field. Note that this method must not create a Chicken object. Instead, a Chicken object must be passed into it as a parameter value.• Define a method called getNumberOfChickens that returns the number of Chicken objects in the ArrayList.• Define another method also called getNumberOfChickens. This one takes a single parameter of type int representing a price per Kilogram and returns the number of Chicken objects in the collection whose pricePerKilo is less than or equal to the value of the parameter.• Define a method called list that prints out, via System.out, the details…

Create the Singly Linked List after having executed the following methods. Each item must have a headand tailreference. Whenever a method is not expected or invalid, write Exception. Only the process not the code •addHead("Dancing") •addHead("Backup") •addHead("Backup") •addTail("Backup") •addTail("Backup") •removeHead()
