title: Many elements of <init-param>,how to determine their order?
body: <p>there are three  in web.xml </p>
  
  <pre><code>&lt;init-param&gt;
      &lt;param-name&gt;user&lt;/param-name&gt;
      &lt;param-value&gt;root&lt;/param-value&gt;
  &lt;/init-param&gt;
  &lt;init-param&gt;
      &lt;param-name&gt;password&lt;/param-name&gt;
      &lt;param-value&gt;1234&lt;/param-value&gt;
  &lt;/init-param&gt;
  &lt;init-param&gt;
      &lt;param-name&gt;dept&lt;/param-name&gt;
      &lt;param-value&gt;z0&lt;/param-value&gt;
  &lt;/init-param&gt;
  </code></pre>
  
  <p>The result of each run is </p>
  
  <pre><code>password:1234
  dept:z0
  user:root
  </code></pre>
  
  <p>They are random loading, or what order?</p>
  
  <p>Thank you seniors.</p>
