A software company that writes applications used to land- scape property wants to add a feature to its application that helps users design brick walls around their property. Write an application that will display a brick wall that is 10 bricks high and 9 bricks wide. You must leave some room between each brick, and every other row must be offset horizontally by half a brick from the bricks in the adjacent row. The completed application should appear as in Fig. 20.32.

a) Copying the template to your working directory. Copy the C:Examples Tutorial20ExercisesBrickWall directory to your C:SimplyJava directory.
b) Opening the DrawJPanel template file. Open the template file DrawJPanel.java in your text editor.
c) Cycling through each row and column of bricks. Inside the drawBricks method (starts at line 45), start an outer for loop to cycle through each row of bricks before the repaint method call (line 58). The counter should start at 0 and iterate through 9 (inclusive), because there are a total of 10 rows. Inside the outer for loop, declare a new int variable y. Initialize this variable to 25 times the row variable. Then begin an inner for loop to iterate through each column of bricks. This for loop should also start at 0 and iterate through 9 (inclusive). Since some rows only have 9 columns of bricks, some bricks will be printed outside of the drawingJPanel. However, these bricks will be invisible to the application user, so you will not remov
