hi, i have twomethod in a java class named polynomail.I wanted to pass the value generated in constructPolynomial()method to displaySelf()method. How do i do that.Below is the prigram i have written so far.. and even i wanted to findout the value of ax^2+ bx + c in a method named functionvalue().Thank you very much in adavnce

import java.util.Scanner;

class Polynomial {

private double quadratic_co; private double linear_co; private double constant; public Polynomial(){ } public void constructPolynomial(){ Scanner scan = new Scanner(System.in); System.out.println("Enter the coefficient of the quadratic term:"); quadratic_co = scan.nextDouble(); System.out.println(); System.out.println("Enter the coefficient of the linear term:"); linear_co = scan.nextDouble(); System.out.println(); System.out.println("Enter the coefficient of the constant term:"); constant = scan.nextDouble(); } /*public double functionValue(double x,double value, double constant){

value =( (x*x)*quadratic_co) + (x* linear_co)+ constant; return value;

}*/

public void displaySelf(double quadratic_co, double linear_co, double constant ){

} public class Assi3 { public static void main(String args[]) { Polynomial p = new Polynomial(); p.constructPolynomial(); //p.functionValue(4.0); p.displaySelf(); } }
