Main issues with the following code:Im not sure if its reading the file correctly because its adding all terms together. In other words the the first line of terms is adding the second line of terms but thats not my intention. Each line of term should have their own polynomial expression as shown below Basic specifications : The code should add the polynomial numbers using a linked list. Java . Keep in mind the polynomials will be gotten from a file. Things to keep in mind the list should be in decending order and traverse the list after all coefficient/exponent pair Term nodes from one input line have been inserted. Here are the specifications //The Polynomial class would likely have a single private data member (reference to class Term) called head. //The Term class would likely have three private data members (coefficient and exponent of type int) and next of type reference to Term. //The latter class would also have the following public methods: constructor(s), gets and sets for each data member, and perhaps a formatting method with the special output requirements. An example of input is 7 1 2 4 6 2 -3 2 -1 -1 3 Negative negative pair signals the termination ***NO doubly linked list , it should be a single linked list ** Input file contains the following : 7 1 2 4 6 2 -3 2 -1 -1 3 ----> 2x^4 - 3x^2 +6x^2 + 7x 5 1 2 3 6 0 -3 2 -1 -1 3 ----> 2*X^3 + (-3)*X^2 + 5*X + 6 // thats the ouput for one line of the the file , each line of the file should have one polynomial output Code import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; public class Polynomial { private Term head; // Constructor for creating an empty polynomial object public Polynomial() { head = null; } // Method for adding a term to the polynomial, this is inside the polynomial term public void addTerm(int coefficient, int exponent) { // Create a new term object Term newTerm = new Term(coefficient, exponent); // If the polynomial is empty, set the new term as the head if (head == null) { head = newTerm; } else { // Traverse the polynomial until we find the correct position for the new term Term current = head; Term previous = null; while (current != null && current.getExponent() > exponent) { previous = current; current = current.getNext(); } // If a term with the same exponent already exists, add the coefficients if (current != null && current.getExponent() == exponent) { current.setCoefficient(current.getCoefficient() + coefficient); } else { // Otherwise, insert the new term into the polynomial if (previous == null) { head = newTerm; } else { previous.setNext(newTerm); } newTerm.setNext(current); } } // Method for formatting the polynomial as a string public String toString() { StringBuilder sb = new StringBuilder(); if (head != null) { sb.append(head.toString()); Term current = head.getNext(); while (current != null) { if (current.getCoefficient() > 0) { sb.append(" + "); } else { sb.append(" - "); } sb.append(current.toString()); current = cur.
