I am trying to use the parameterized constructor in Newton's Lab2. The signature is: public Body(int size, double mass, Vector velocity, Color color)
I enter something like 20, 20, new Vector (90, 1.0), new Color (12,12,12) and I get the error cannot find symbol - class Color.
The color class has been imported. I have also tried the following parameters for color and they do not work either. new Color (12,12,12,1), color.Red, defaultColor.
Scenario code: I did not change it from the second edition downloads
import greenfoot.*;
import java.awt.Color;
import java.util.List;
/**
* A 'Body' is any kind of object in space that has a mass. It could be
* a star, or a planet, or anything else that floats around in space.

*/
public class Body extends SmoothMover
{
// constants
private static final double GRAVITY = 5.8;
private static final Color defaultColor = new Color(255, 216, 0);
// fields
private double mass;
/**
* Construct a Body with default size, mass, velocity and color.
*/
public Body()
{
this (20, 300, new Vector(0, 1.0), defaultColor);
}
/**
* Construct a Body with a specified size, mass, velocity and color.
*/
public Body(int size, double mass, Vector velocity, Color color)
{
this.mass = mass;
addToVelocity(velocity);
GreenfootImage image = new GreenfootImage (size, size);
//color = new Color (12,12,12);
image.setColor (color);
image.fillOval (0, 0, size-1, size-1);
setImage (image);
}
I can send a snapshot of the error if needed.
