Java Programming. I'm working on making a Polynomial class and Node class. One of the methods I need for it is a Polynomial (String poly) which needs to take the poly argument in a string representing a polynomial, in standard, decreasing term form (6x^3 + 7x + 1). This method needs to be responsible for creating the individual nodes and chaining them together appropriately. This is my Node Class. and this is my polynomial class so far. public class Node \{ public int exponent; public int coefficient; public Node next; Node (int coefficient, int exponent) \{ this.coefficient = coefficient; this.exponent = exponent; \}/ End Node thol public int getExponent () \{.
