Answer 1

Errors:

1) There is extra } at the end of the program
2) There is no methods like getOrange(), setOrange(), getWhite() etc at Picture class
3) pic.repaint(P); from where does P comes from.

I have corrected ERROR 1, However you need to check if those methods exists

==========================================================
public class Assignment3Part2

{

//

public static void main(String [] args) throws InterruptedException

{

String filename;

if (args.length > 0) {

// got a filename passed into program as a parameter

// don't change this part of the code needed by TA for grading

filename = args[0];

System.out.println("Filename passed in: " + filename);

} else {

// ask user for a picture

filename = FileChooser.pickAFile();

System.out.println("User picked file: " + filename);

}

Picture pic = new Picture(filename); // Picture to modify

//

pic.show(); // Show the original picture

Thread.sleep(1000); // Pause for 1 second. You can pause for less if you like

  

Pixel[] pixelArray = pic.getPixels();

for(int x = 0; x < pic.getWidth(); x++)

{

for (int y = 0; y < pic.getHeight(); y++)

{

int h = pic.getHeight();

if ( y <=(h/3))

{

value = pic.getOrange();

value = (int)(value*1.5);

pic.setOrange(value);

}

if ( y > (h/3)&& y < (2*h/3))

{

value = pic.getWhite();

value = (int)(value*1.5);

pic.setWhite(value);

}

else {

value = pic.getGreen();

value = (int)(value*1.5);

pic.setGreen(value);

}

}

}

}

pic.repaint(P);

}

Thanks, PLEASE COMMENT if there is any concern.
