    I am currrently new to programming so please bare with me.

    This is for my Intro to Java programming class, the instructions are displayed in the picture.

    import java.util.Scanner;
    public class QuadEval
    {
    public static void main(String[] args)
    {
    int a, b, c, x;
    Scanner s = new Scanner(System.in);
    System.out.println("Given quadratic equation:ax^2 + bx + c");
    System.out.print("Enter a:");
    a = s.nextInt();
    System.out.print("Enter b:");
    b = s.nextInt();
    System.out.print("Enter c:");
    c = s.nextInt();
    System.out.print("Enter x:");
    x = s.nextInt();
    System.out.println("Given quadratic equation:"+a+"x^2 + "+b+"x + "+c);

    I am not sure if i am doing it right and what the next steps are, any help will be appreciated.

    Everything looks syntactically correct. Have you run it to see if performs as expected? The next step would be to calculate the value of z based on the independent variable x and the values of the coefficients a, b, and c.

    I can't tell if your supposed to calculate the value or simply create a String as described in the example and then pass it on to some method that the instructor will provide. I can't really help much here. I would recommend you talk to your instructor or some of your classmates to get a clarification.

    Regards,

    This is the required format for the output after running the code, I'm not sure if this helps.

    According to the image it looks more like this.

    [a=2.0][b=5.0][c=1.0][x=1.0]

    Like I suggested before. All you may need to do is create that parameter string and submit it. You really should talk to someone who is involved with this class.

    Regards,
    Jim
