      <ul>
        <li>Knowledge of class diagram notation</li>

      </ul>
    </li><li><i>Object-Oriented Design</i> 
      <ul>
        <li>Knowledge of the association relationship</li>
      </ul>
  </li></ul>
  <p> <b><i>Goals:</i></b> Reinforce the your ability to model associations between 
    classes using UML
  </p><p> <b><i>Outcomes:</i></b> You will master the following skills: 
  </p><ul>

    <li>Produce UML class diagrams that model associations between classes
</li></ul>
</blockquote> 
    
<h3>Description</h3>

<p>Use Eclipse,  <a href="http://horstmann.com/violet/" target="externalWindow">Violet</a>,<em> </em>PowerPoint, or
  another tool of your choosing to produce a UML class diagram that  models the
  following personal computer:</p>
<ul>
  <li>The personal computer <code></code> consists of a monitor, a system box,
  a keyboard, and a mouse.</li>

  <li>The system box consists of a chassis, zero or more
    hard disks, and a motherboard. </li>
  <li>The motherboard consists of one processor and one memory.</li>
</ul>
<p>The components of the personal
computer contain the following information:</p>
<ul>
  <li>Personal computer: 
    <ul>
      <li>A string that represents the name of the model</li>
    </ul>

  </li>
  <li>Monitor: 
    <ul>
      <li>A double  that represents the size of the monitor in inches</li>
    </ul>
  </li>
  <li>Keyboard: 
    <ul>
      <li>A string that represents the type of connector (<code>"PS/2"</code> or <code>"USB"</code>)</li>

    </ul>
  </li>
  <li>Mouse: 
    <ul>
      <li>An integer that represents the number of mouse buttons</li>
      <li>A string that represents the type of connector (<code>"PS/2"</code> 
    or <code>"USB"</code>)</li>

    </ul>
  </li>
  <li>Hard disk: 
    <ul>
      <li>A double  that represents the storage capacity in megabytes</li>
      <li>A double  that represents  the rotational speed in
     revolutions per minute</li>
    </ul>
  </li>

  <li>Chassis: 
    <ul>
      <li>An integer that represents the number of bays</li>
      <li>Three double values that represent the dimensions (height, width, and depth) in 
    inches</li>
      <li>A double  that represents the  power supply rating in watts</li>
    </ul>
  </li>
  <li>Processor: 
    <ul>

      <li>A string that represent the processor name</li>
      <li>An integer that represents the processor speed in hertz</li>
      <li>An integer that represents the 
     bus speed in hertz</li>
    </ul>
  </li>
  <li>Memory: 
    <ul>
      <li>A string that represents the  architecture (<code>"DDR"</code>, <code>"RDRAM",</code> 
    or <code>"SDRAM"</code>) </li>

      <li>An integer that represents the amount of memory in bytes</li>
    </ul>
  </li>
</ul>
<p>The UML class diagram should include class 
  attributes, class associations, association multiplicities,
  and association attributes. Use Sun's coding conventions when naming classes and attributes. </p>
<p>
Save the UML class diagram in a SVG, GIF, or JPG format in a file named <em>computer-uml</em>.</p>
<h3>Submission</h3>

<p>Upon completion, submit <strong>only</strong> the SVG, GIF, or JPG file <em>computer-uml</em>. The  extension of this file will depend on the format of the image. </p>

<h3>Description</h3>

<p>Use Eclipse, <a href="http://horstmann.com/violet/" target="externalWindow">Violet</a>, 
  PowerPoint, or another tool of your choosing to produce a UML class diagram 
  that shows the specialization/generalization relationships between the following 
  classes. Use the shortest form to show only the name of each class. Use Sun's coding conventions when naming classes:</p>
<ul>
  <li>Fish</li>
  <li>BlueWhale</li>

  <li>Dog</li>
  <li>Animal</li>
  <li>Eagle</li>
  <li>Shark</li>
  <li>Mammal</li>
  <li>GrayWhale</li>

  <li>Bird</li>
  <li>Whale</li>
</ul>
<p>Use the following resource to obtain information about these names:</p>
<ul>
  <li><a href="http://www.eNature.com" target="externalWindow">eNature.com</a></li>
</ul>
<p>Save the UML class diagram in a SVG, GIF, or JPG format in a file named <em>animals-uml</em>.</p>
