Consider the partial class declarations below.

public class Pixel $\{$

$//$ instance variables and

$//$ constructors not shown

public int getRed$()\{...\}$

public int getGreen$()\{...\}$

public int getBlue$()\{...\}$

public void setRed$($int value$)\{...\}$

public void getGreen$($int value$)\{...\}$

public void getBlue$($int value$)\{...\}$

$//$ other methods not shown

$\}$

public class ImagePlus $\{$

private Pixel$[][]$ pixels;

$//$ other instance variables,

$//$ constructors, and methods not shown

$//$to be implemented

public void darkerDarks$()\{...\}$

$\}$

We want to add a method to the ImagePlus class called darkerDarks$().$ This method would change all Pixel objects with an average amount of RGB less than $25$ to a completely black Pixel. In other words, if the average of red, green, and blue in a Pixel object is less than $25,$ the red, green, and blue values would be changed to zero. This would happen for all Pixel objects in the ImagePlus object.
