#exercise 11

Can anyone help me with the Chapter - Exercise 11 Solution. This is what I have done so far. I'm wondering if there is a better way to resolve the exercise. 

If you don't have the book here it is the exercise:

11. Exercise 4 in Chapter 2 asks you to write a graphics program thal produces a diagram of a simple frame house. If you wanted to make the DrawHouse program easy to change, what named constants shou ld you define to provide the necessary flexibility? Rewrite the program so that it uses these named constants rather than explicit coordinate values.

Code from Exercise 4, Chapter 2:

import acm.graphics.*; import acm.program.*; import java.awt.*;

public class JHouse extends GraphicsProgram{ public void run(){ GRect rectWalls = new GRect(((getWidth() - 300)/2), ((getHeight()-120)/2), 300, 120); GRect rectDoor = new GRect(((getWidth() - 50)/2), ((getHeight()-80)/2+20), 50, 80); GRect windLeft = new GRect(((getWidth() - 40)/2-90), ((getHeight()-40)/2), 40, 40); GRect windRight = new GRect(((getWidth() - 40)/2+90), ((getHeight()-40)/2), 40, 40); GLine roofRight = new GLine(527,177,370,50); GLine roofLeft = new GLine(228,177,369,50); GLine windFrameR = new GLine(287,255,287,216); GLine windFrameL = new GLine(467,255,467,216); GOval doorHandle = new GOval(387,255,7,7); add(rectWalls); add(rectDoor); add(windLeft); add(windRight); add(roofRight); add(roofLeft); add(windFrameR); add(windFrameL); add(doorHandle); } }

Social Activism: Explore and Reflect

  Journal Activity #3

  Students will explore and reflect how their daily lives may affect the outcomes of genocide. Students will draw connections between the geopolitical undertones from the current crisis in Darfur to the effects of genocide.

  Materials: Darfur Now and Journal

  Objectives:

·        Compare the motivations of Darfur Now activists to their own motivations for action.

·        Identify how the ideas represented in Darfur Now connect to the choices they make in their owlives.

·        Synthesize and express their understanding of themes presented in Darfur Now.

  Procedure:

  ·        Students should research and learn about another genocide that has occurred since the1948 Convention.

·        Students should identify the root causes of that genocide.

·        Write a 2 page response on their idea of a solution to present-day conflicts affected by

geopolitics. What are larger policy issues that need to be reinforced? What can students do on an individual basis?

·        Students will formally present their solution in class. The length of the formal presentation is 5-7 minutes.

    Purpose of Explore and Reflect:

·        This help students understand social activism.

·        Improve students’ critical thinking and critical analysis of literature.

·        Allow students to practice articulating responses (written and verbal).

·        They allow the instructor to assess participants’ interests and learning.
