This is the solution to step 1 of the Stanford CS106A Breakout game assignment, setting up the bricks.

BreakoutBrickSetup

//adding an individual brick object
	private GRect brick;
	
	//drawing all the bricks necessary for the game
	private void drawBricks(double cx, double cy) {				
		
		/*need to have several columns in each row
		 * so there need to be two for loops, 
		 * one for loop for the rows and one for loop for the columns.
		 */ 
		
		for( int row = 0; row < NBRICK_ROWS; row++ ) {
			
			for (int column = 0; column < NBRICKS_PER_ROW; column++) {
				
				/* To get the x coordinate for the starting width:
				 * 	start at the center width, 
				 * 	subtract half of the bricks (width) in the row,  
				 * 	subtract half of the separations (width) between the bricks in the row,
				 * now you're at where the first brick should be, 
				 * so for the starting point of the next bricks in the column, you need to: 
				 * 	add a brick width 
				 * 	add a separation width
				 */
				
				double	x = cx - (NBRICKS_PER_ROW*BRICK_WIDTH)/2 - ((NBRICKS_PER_ROW-1)*BRICK_SEP)/2 + column*BRICK_WIDTH + column*BRICK_SEP;
				
				/* To get the y coordinate of the starting height:
				 * 	start at the given length from the top for the first row,
				 * 	then add a brick height and a brick separation for each of the following rows
				 */
				
				double	y = cy + row*BRICK_HEIGHT + row*BRICK_SEP;

				brick = new GRect( x , y , BRICK_WIDTH , BRICK_HEIGHT );
				add (brick);
				brick.setFilled(true);
				
				//Setting colors depending on which row the bricks are in
				
				if (row < 2) {
					brick.setColor(Color.RED);
				}
				if (row == 2 || row == 3) {
					brick.setColor(Color.ORANGE);
				}
				if (row == 4 || row == 5) {
					brick.setColor(Color.YELLOW);
				}
				if (row == 6 || row == 7) {
					brick.setColor(Color.GREEN);
				}
				if (row == 8 || row == 9) {
					brick.setColor(Color.CYAN);
				}
			}
		}

Can you add a lot more comments to your code? I did this a while ago, so I'm not sure what your code is for...

Now, it's much better :) Make sure to add good comments to your code moving forward so anyone reading it will understand what you're doing.
