title: for loop to jstl forEach
body: <p>How to convert below <code>for</code> loop to a <code>jstl</code> <code>foreach</code>:</p>
  
  <pre><code>for(int i = 0 ; i&lt;=21; i+=3){
    // print foo
  }
  </code></pre>
  
  <p>This is what I have so far:</p>
  
  <pre><code>&lt;c:forEach varStatus="loop" begin="0" end="21"&gt;
    // display foo
  &lt;/c:forEach&gt;
  </code></pre>
