- Java Code: How to implement logic for ParseIf ParseFor, ParseWhile, ParseDoWhile, ParseDelete, ParseReturn, and ParseFunctionCall where all of the Node data structure correct, parses correctly, throws exceptions with good error messages. Make sure to write block of codes for these methods.OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly without any errors and provide the code with the screenshots of the outputs. The code must have a function that takes a pair of strings (tuple) and returns a unit. Make sure to have the following methods below: -Push integers, strings, and names on the stack -Push booleans -Pushing an error literal or unit literal will push :error: or :unit: onto the stack, respectively -Command pop removes the top value from the stack -The command add refers to integer addition. Since this is a binary operator, it consumes the top two values in the stack, calculates the sum and pushes the result back to the stack - Command sub refers to integer subtraction where if top two elements in the stack are integer numbers, pop the top element(y) and the next element(x), subtract y from x, and push the result x-y back onto the stack…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,…
- Complete ArrayStack.java, an array-based implementation o the Stack.java interface. Modify only the bodies of the following methods in the ArrayStack class: push pop top isEmpty isFull Nothing else should be modified in ArrayStack. Write the class ArrayStackTest to test your implementation. Print only the names of the tests and error messages. Give the test method meaningful names (e.g., emptyStackTest). Test push, pop, top, and isEmpty immediately after the stack has been instantiated. Push an element on an empty stack. Test pop, top, and isEmpty. Instantiate a stack with initialCapacity of 1. Push two elements. Check capacity. Other tests you deem necessary.public interface StackInterface void push (T element) throws StackoverfloWException; void pop () throws StackUnderflowException; T top () throws StackUnderflowException; boolean isFul1 (); boolean isEmpty(); Show what is written by the following segments of code (see printın on the code), given that iteml, item2, and item3 are int variables, and ali is an object that fits the abstract description of a stack as shown above StackInterface.

- File TesSLL.java contains a driver that allows you to experiment with these methods. Compile and run TestSLL, and play around with it to see how it works. Then add the following methods to the SinglyLinkedList class. For each, add an option to the driver to test it. Do this in incremental steps!! This means, implement and test the methods one at a time.Containers that support random-access iterators can be used with most but not all Standard Library algorithms. What is the exception?5- Write an efficient java method that computes and returns the height from node t in a btree of any degree. . Please write proper comments in your java code. Your java code should not read or print anything. Assume btree node is defined as follow: private class node{ int count, data(); node parent, link[]:} // end class node private int height(node t){
- public static CS150 getInstance(){ //TODO implement a single return null; }The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.- Write a Polynomial class that has methods for creating a polynomial, reading and writing a polynomial, and adding a pair of polymomials - In order to add 2 polynomials, traverse both lists, If a particular exponent value is present in either one, it should also be present In the resulting polynomial unless its coefficient is zero. java submit as a text dont use others answers please attach screenshot of output Thank you!!!
