IN JAVA PLEASE!!!

PLEASE READ AND DO IT CORRECTLY, IT HAS 2 PARTS: MAIN PROGRAM AND EXTRA CREDIT, I WILL ASK ANY QUESTION THAT MIGHT HAVE IF THE CODE CAN'T RUN SO PLEASE CHECK IF I HAVEN'T UPVOTE YOUR ANSWER, I WILL UPVOTE FOR RIGHT ANSWER.

Your assignment is to make a class called Poly that implements addition, negation, subtraction, and any other incomplete method shown in the Poly starter code. You may include any other methods needed to make the driver function.

A polynomial is an arithmetic expression of the form:

a_nxⁿ + + a₂x² + a₁x¹ + a₀

where x is a variable that can take on different numeric values and a_n , , a₂, a₁ , and a₀ are constants called the coefficients of the polynomial. The highest exponent with non-zero coefficient, n, is called the degree of the polynomial. For example, 0x² + 4x + 5 is normally written as 4x + 5 and has degree 1.

Note: A polynomial whose coefficients are all zero has degree -1.

One way to represent a polynomial is to use an array to hold the coefficients. A polynomial of degree n has n + 1 coefficients. An array of size k can hold the coefficients for a polynomial of degree k 1 (or a smaller degree).

For instance:

4x5 + 2x4 + 3x2 - 4x + 5

can be represented as this array:

Coefficients are in reverse order in the array.

For extra credit: implement multiplication and division (both quotient and remainder).
