</blockquote>
<h3>Background </h3>
<p>This assignment asks you to model a coffee store application. </p>
<h3>Description</h3>
<p><em>Gourmet Coffee</em> is a store that sells coffee from countries around
the globe. It also sells coffee brewing machines and other accessories for coffee
consumption. The <em>Gourmet Coffee System</em> maintains a product catalog,
processes orders, and tracks the store's sales. </p>
<p>The catalog maintains the following information about the store's products:</p>
<ul>
<li>Coffee
<ul>
<li>Code</li>
<li>Description</li>
<li>Price</li>
<li>Country of origin</li>
<li>Type of roast</li>
<li>Flavor</li>
<li>Aroma</li>
<li>Acidity</li>
<li>Body</li>
</ul>
</li>
</ul>
<ul>
<li>Coffee brewer
<ul>
<li>Code</li>
<li>Description</li>
<li>Price</li>
<li>Model of the brewer</li>
</ul>
</li>
<ul>
<li>Type of the water supply: <em>Pour-over</em> or <em>Automatic</em></li>
<li>Capacity: number of cups</li>
</ul>
</ul>
<ul>
<li>Coffee accessory
<ul>
<li>Code</li>
<li>Description</li>
<li>Price</li>
</ul>
</li>
</ul>
<p>The following tables show some of the products sold by<cite> Gourmet Coffee</cite>.
</p>
<blockquote>
<table cellpadding="2" width="75%" cellspacing="2" border="0">
<tr>
<td><img width="570" height="165" src="images/table-coffee.gif" alt="Figure 1 Coffee ">
</td>
</tr>
<tr>
<td><strong>Figure 1</strong><em> Coffee </em></td>
</tr>
</table>
</blockquote>
<blockquote>
<table cellpadding="2" width="75%" cellspacing="2" border="0">
<tr>
<td><img width="492" height="120" src="images/table-brewer.gif" alt="Figure 2 Coffee brewers">
</td>
</tr>
<tr>
<td><strong>Figure 2</strong><em> Coffee brewers</em></td>
</tr>
</table>
</blockquote>
<blockquote>
<table cellpadding="2" width="69%" cellspacing="2" border="0">
<tr>
<td><img width="290" height="103" src="images/table-accessory.gif" alt="Figure 3 Coffee accessories"></td>
</tr>
<tr>
<td><strong>Figure 3</strong><em> Coffee accessories</em></td>
</tr>
</table>
</blockquote>
<p>The <em>Gourmet Coffee System</em> processes orders.
An order contains a list of products, their quantities, and the total cost.
The following is an
example
of
an order:</p>
<blockquote>
<table cellpadding="2" width="75%" cellspacing="2" border="0">
<tr>
<td><img width="375" height="103" src="images/table-order.gif" alt="Figure 4 Order"></td>
</tr>
<tr>
<td><strong>Figure 4</strong><em> Order</em></td>
</tr>
</table>
</blockquote>
<p>In the <em>Gourmet Coffee System</em>, the user can:</p>
<ul>
<li>Display the catalog: lists the code and description of
each product </li>
<li> Display a product</li>
<li>Display the current order: lists quantity, code, and price of each product
in the current order, and the total of the order.</li>
<li>Add a product to the current order—if the specified product is already
part of the order, this command will modify the quantity of that product</li>
<li> Remove a product from the current order</li>
<li>Register the sale of the current order—this command adds the order
to the store's sales and empties the current order</li>
<li> Display the sales: lists all the orders that have been sold</li>
</ul>
<p>Run the sample executable that is provided to learn more about the <em>Gourmet
Coffee System</em>.</p>
<h3>Files</h3>
<p>Following is a sample executable of the <em>Gourmet Coffee System</em>.</p>
<ul>
<li><cite><a href="/content/SSD/SSD3/4.2.0.1/normal/pg-class-dsgn/pg-dsgnng-class/assm-exer-mdlng-cof-gou-sys/pool-pr-uml-mdlng/qn-pr-mdlng-gou-cof-sys_v2/handout/gourmet-coffee-sample-executable.jar">gourmet-coffee-sample-executable.jar</a></cite>
— Download this file now. It is a sample executable.</li>
</ul>
<h3>Tasks </h3>
<p>These steps will guide you for completing this assignment:</p>
<ol>
<li><strong>First</strong>, run the sample executable by issuing the following
command at the command prompt:
<blockquote><tt>C:\></tt><kbd>java -jar gourmet-coffee-sample-executable.jar</kbd>
</blockquote>
</li>
</ol>
<ol start="2">
<li><strong>Then</strong>, follow the technique described in page <a href="javascript:ContentByName('pg-mdlng-class');">1.2.5 Modeling
Classes</a> to model the <em>Gourmet Coffee System</em>.
<p> Identify the following:</p>
<ul>
<li>The classes</li>
<li>The association relationships (include direction, multiplicity, and
association attribute)</li>
<li>The specialization/generalization relationships</li>
<li>The attributes of each class</li>
<li>The methods of each class</li>
</ul>
<p>Your class diagram should include:</p>
<ul>
<li>The class of the gourmet coffee application</li>
<li>The accessor methods</li>
<li>The mutator methods if are needed</li>
<li>For the collections:
<ul>
<li> The methods to add and access elements</li>
<li> The methods to remove elements if are needed</li>
</ul>
</li>
<li>The methods that compute other values not included in the attributes.
</li>
</ul>
<p>Use Sun's coding conventions when naming classes, methods, and attributes.</p>
</li>
<li>Use Eclipse, <a href="http://horstmann.com/violet/" target="externalWindow">Violet</a>,
PowerPoint, or another tool of your choosing to draw a UML class diagram.</li>
</ol>
<ol start="4">
<li>Save the UML class diagram in a SVG, GIF, or JPG format in a file named <em>uml-gou-cof</em>. </li>
</ol>
<h3>Submission</h3>
<p>Upon completion, submit <strong>only</strong> the SVG, GIF, or JPG file <em>uml-gou-cof</em>.
The extension of this file will depend on the tool used to create the diagram.
