Chapter 7, Problem 12E

The complete implementation for “Polynomial” class is given below:

//Define "Polynomial" class

public class Polynomial

{

    //Declare required variables   

    private int degree;

    private double[] coefficients;

/* Constructor for "Polynomial" class with argument "max" */

    public Polynomial(int max)

    {

        degree = max;

        coefficients = new double[degree+1];

    }

/* Define method for set the coefficient "a" to "value" */

    public void setConstant(int i, double value)

    {

/* If the value of "i" is greater than or equal to "0" and value of "i" is less than or equal to "degree", then */

        if(i >= 0 && i <= degree)

/* Set given coefficient to given "value" */

            coefficients[i] = value;

    }

/* Define method for returns the polynomial value for given "x" */

    public double evaluate(double x)

    {

        /* Set total to "0" */

        double total = 0.0;

        /* Set the value of x to "1" */

        double xValue = 1.0;

        /* Compute sum for given equation */

        for(int i = 0; i <= degree; i++)

        {

            total += coefficients[i]*xValue;

            xValue *= x;

        }

/* Returns the sum of given polynomial equation for given "x" */

        return total;

    }

    //Define main function

    public static void main(String[] args)

    {

        /* Create object for "Polynomial" class */

        Polynomial p1 = new Polynomial(5);

/* Set a0 = 3 by calling the method "setConstant" */

        p1...
