<h2><A NAME="pgmdesign"></A>Step 2: Design your application</h2>
|
||
|
|
|
||
|
|
<p>When you begin to develop actual applications, use the steps below to take advantage of the strengths of each Java component in your applications.</p>
|
||
|
|
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
|
||
|
|
<li><strong>Design object-oriented applications to reuse and maintain code.</strong>
|
||
|
|
<ul>
|
||
|
|
<li>Break different types of logic into separate Java classes. Some logical types are:
|
||
|
|
<ul>
|
||
|
|
<li>Business processes</li>
|
||
|
|
<li>Data structures and modeling</li>
|
||
|
|
<li>Application flow</li>
|
||
|
|
<li>Database access</li>
|
||
|
|
<li>Web page presentation</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>When possible, design complex logical or data structures as collections of simpler Java objects.</li>
|
||
|
|
<li>When several processes or data structures share "common denominator" variables or functionality, do the following:
|
||
|
|
<ol>
|
||
|
|
<li>Group common variables and functions into a base class.</li>
|
||
|
|
<li>Extend the base class to create more specialized classes.</li>
|
||
|
|
</ol>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li><strong>Design your code to take advantage of the strengths of the Java components.</strong>
|
||
|
|
<ul>
|
||
|
|
<li>Use servlets to perform application logic, call other Java components, and work with Extensible Markup Language (XML).</li>
|
||
|
|
<li>Use JavaServer Pages (JSP) files to create dynamic Web pages.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
</ol>
