    Default Program is running successfully but still getting error message..

    i am trying to construct a pyramid like this (see attachment)

    my code is
    import acm.graphics.*;
    import acm.program.*;
    import java.awt.*;
     
    public class Pyramid extends GraphicsProgram {
     
    /** Width of each brick in pixels */
    	private static final int BRICK_WIDTH = 30;
     
    /** Height of each brick in pixels */
    	private static final int BRICK_HEIGHT = 12;
     
    /** Number of bricks in the base of the pyramid */
    	private static final int BRICKS_IN_BASE = 14;
     
    	public void run() {
     
    		int BaseBrick=BRICKS_IN_BASE, height=BRICK_HEIGHT,weidth=BRICK_WIDTH,x=5,y=300;
    		while(BaseBrick!=0) {
    			drawRow(BaseBrick,x,y,height,weidth);
    			BaseBrick--;
    			y-=12;
    			x+=15;
    		}
    	}
    	private void drawRow(int BaseBrick, int x, int y,int height, int weidth) {
    		for(int i=0;i<BaseBrick;i++){
    		GRect rect = new GRect(x,y,weidth,height);
    		add(rect);
    		x+=30;
    		}
    	}
    }

    Not many of us have the third party packages you are using. Can you copy and paste here the error messages you are getting. Its hard to copy a String from an image for searching the text of your code.

    As far as I can tell those errors are occurring in the pyramid_final class, not the Pyramid class. I don't see a clear execution order here, what does the rest of the code look like?
