This assignment is divided in 2 parts:

Consider a class Polynomial, which represents polynomials of a single variable up to the fourth power (x4). The sole instance variable of a Polynomial is an array of size 5, that stores doubles. Each element of the array represents the coefficients of the Polynomial at the corresponding power. For example:

Element 0 is the coefficient of the x0 term

Element 1 is the coefficient of the x1 term

Element 2 is the coefficient of the x2 term

Element 3 is the coefficient of the x3 term

Element 4 is the coefficient of the x4 term

Thus the polynomial 3.0 – 1.0x +2.0x2 would be represented by the array:

3.0 -1.0 2.0 0.0 0.0

Write the class Polynomial that includes the following methods:

- A default constructor that initializes all coefficients to zero.
- A constructor that takes five doubles as its formal parameters and initializes the coefficients to the value of the corresponding parameters.
- A constructor that takes an Polynomial object as its formal parameter and creates a new polynomial that has coefficients that are identical to the Polynomial object passed in.
- An accessor method that takes in a parameter n and returns the nth coefficient.
- A mutator method that has 2 formal parameters n and a new coefficient, and sets the nth coefficient to the new value being passed in.
- A method called add that computes the sum of two polynomials and returns a new polynomial. The signature of this method should be: public Polynomial add(Polynomial p)
- A method called evaluate that computes the value of the polynomial with the value passed as a parameter. The signature of this method should be: public double evaluate(double x)
- A method called derivative that returns the derivative of the polynomial. The signature of this method should be: public Polynomial derivative()
- A method called numberOfTerms that returns the number of non-zero terms of the polynomial.
- A toString method such that the statement System.out.println(somePolynomialObject) would display the polynomial as an equation but only the non zero terms are displayed and the + sign for the first terms does not appear. For example:

if the array contains 3.0 -1.0 2.0 0.0 0.0 The output should be: 3.0 – 1.0x^1 + 2.0x^2

if the array contains 7.0 0.0 2.0 0.0 4.0 The outputshould be: 7.0 + 2.0x^2 + 4.0x^4

Write a driver program that will :

- Create an array of 8 Polynomials
- Prompt the user for the coefficients for the first two polynomials (store these in locations 0 and 1 of your array of Part 1 above)
- Randomly generates the coefficients for the next 3 polynomials (store these in locations 2, 3 and 4). The coefficicents should be between 0.0 and 100.0.
- In location 5 of your array, stores the sum of the polynomials in location 0 and 2
- In location 6 of your array, stores a polynomial whose coeficients are 3 times those of the polynomial in location 1
- In location 7, store the derivative of the polynomial in location 4
- Prompt the user for a double value x, then print the 8 polynomials along with the number of terms in each polynomial and the value of the polynomial when evaluated with x. For example if the user entered x=3.0, the output for the polynomial

3.0 -1.0 2.0 0.0 0.0 should be :

Polynomial 3.0 – 1.0x^1 + 2.0x^2 has 3 terms and evalutes to 18.0 for x = 3.0
