New code in Java

1. A polynomial can be represented as a linked list, where each node called a poly Node contains the coefficient and the exponent of a term of the polynomial. For example, the polynomial 4x3+3x25 would be represented as the linked list: - 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
