title: Assigning variable and then using variable in parameters?
body: <p>I'm doing these free online Stanford classes and learning Java.  I'm stuck on something and haven't been able to figure it out.  I think there must be something wrong with my logic.  Please check out the code below.  I commented it, so hopefully you can understand what I'm trying to do there.</p>
  
  <pre><code>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;
  
  /*  Width 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;
  
  /** The Width of the Base in px  */ 
      double baseInPx = BRICKS_IN_BASE * BRICK_WIDTH;
  
  /** Taking the width of the window minus the width of the base and dividing by two 
   * to find the x axis starting point)   
   */
      double firstBrick = (getWidth() - baseInPx) / 2;
  
  /* giving the y axis a variable name  */
          double baseHeight = getHeight();
  
      public void run() {
  
          add(new GRect(firstBrick,baseHeight,BRICK_WIDTH, BRICK_HEIGHT));
  
      }   
  
  }
  </code></pre>
  
  <p>I'm thinking I must be doing something wrong in my formatting in this line:</p>
  
  <pre><code>double firstBrick = (getWidth() - baseInPx) / 2;
  </code></pre>
  
  <p>The problem is that my variable in the x axis is not working.  If I hard code a number there, the rect shows up, but not with <code>firstBrick</code></p>
  
  <p>Thanks for your help!</p>
  
  <p>EDIT: Thank you all for your help!  Pretty much every one of you were right.  I just learned something!</p>
