Start on the Applet

Answer:

You should get something like this:

House        --- ( 65, 100) width=110, height=110
Door         --- (120, 165) width= 25, height= 40
Left Window  --- ( 90, 115) width= 30, height= 30
Right Window --- (130, 115) width= 30, height= 30
Tree Trunk   --- (255, 100) width= 10, height=100

With this information, you can start coding the applet. The code starts by defining variables that contain the above coordinates. Give the variables names that show their use. For example houseX is the X coordinate of the left edge of the house. houseW is the width of the house.

import javax.swing.JApplet;
import java.awt.*;

// assume that the drawing area is 350 by 250
public class HouseRectangles extends JApplet
{
  final int width  = 350, height = 250;
  final int houseX =  65, houseY = 100, houseW = 110, houseH = 110 ;
  final int doorX  = 120, doorY  = 165, doorW  =  25, doorH  =  40 ;
  final int lWindX =  90, lWindY = 115, lWindW =  30, lWindH =  30 ;
  final int rWindX = 130, rWindY = 115, rWindW =  30, rWindH =  30 ;
  final int trunkX = , trunkY = , trunkW = , trunkH =  ;
  
  public void paint ( Graphics gr )
  { 

     gr.drawRect( houseX , houseY , houseW, houseH); // house
     gr.drawRect( doorX  , doorY  , doorW , doorH ); // door
     gr.drawRect( lWindX , lWindY , lWindW, lWindH); // lwind
     gr.drawRect( rWindX , rWindY , rWindW, rWindH); // rwind
     gr.drawRect(  ,  ,  , ); // trunk
  }
}

You may think that it would be just as easy to put the numbers directly into the drawRect() method. But if you need to make adjustments later on, it is very useful to have names for the various values you wish to change.
