Create a new project in jdoodle called "Assignment3". For this assignment you will be creating a total of 2 classes that meet the definitions below. This assignment will allow the user to enter in the coefficients for a polynomial function of degree 2. The user will then be asked to enter a number. The program will use that number as an argument to the function, and will print the corresponding function value. Keep in mind that a second degree polynomial function in general form looks like:

f(x) = ax² + bx + c (here a is the coefficient of the quadratic term, b is the coefficient of the linear term, and c is the constant)

Data (attributes) - all have private access

double quadraticCoefficient (this is the coefficient of the quadratic term of the polynomial)

double linearCoefficient (this is the coefficient of the linear term of the polynomial)

double constant (this is the constant of the polynomial)

Methods (behaviors) - all have public access

constructor:

Arguments:

None

Return

None

Behavior

Calls Polynomial's constructPolynomial instance method

constructPolynomial:

Arguments:

None

Return

None

Behavior

Allows user to enter the necessary coefficients and the constant term for the polynomial, and sets the attributes accordingly

functionValue:

Arguments:

double arg

Return

double

Behavior

Calculates and returns the function value using the argument arg (for example, if the user entered the polynomial 3x² + 2x + 7, then functionValue(3) would return 40)

displaySelf:

Arguments:

None

Return

None

Behavior

Neatly displays the polynomial entered by the user

class Assignment3

Methods

public static void main(String[] args):

Arguments:

String[] args

Return:

None

Behavior (see image below for clarification):

The polynomial is constructed

The user is asked for the argument to the function

The polynomial is displayed

The function value (based on the argument and Polynomial entered) is displayed
