(IN JAVA):

Given this code (copy below):

------------------------------------------------------------------------------------------

public class Colour { static final Colour RED = new Colour(255, 0, 0); static final Colour BLUE = new Colour(0, 0, 255); private int red; private int green; private int blue; public static void main(String[] args) { /**  * //run this to see if toString method is working. Output should be: #ff0000  *  * Colour c = new Colour(255, 0, 0);  * c.toString();  * System.out.println(c);  */   /**  * //run this to see if the add method is working. Output should be: Color(25,100,255)  *  * Colour c = new Colour(25,100,500);  * Colour newColour = c.add(Colour.BLUE);  * return newColour;  */   } public Colour(int red, int green, int blue) { if (blue < 0) blue = 0; if (blue > 255) blue = 255; this.blue = blue; if (green < 0) green = 0; if (green > 255) green = 255; this.green = green; if (red < 0) red = 0; if (red > 255) red = 255; this.red = red; } }

Create a method called toString that takes no parameters. This method returns a string representation of the color in the form #rrggbb where rr, gg, and bb are the red, green, and blue component values expressed as hexadecimal digits. [hint: use Integer.toHexString()] to convert an integer value to a hexadecimal.

&

Create a method called add that takes a Color object as a parameter & returns a new Color value that is the sum of this color and the color specified as a parameter. The value of the red components of the two colors are added (The same for the green and blue). Any result greater than 255 is set to 255.

[Examples of what is being inputted & the expected output can be found in the main method]
