title: Java dynamic array sizes?
body: <p>I have a class - xClass,  that I want to load into an array of xClass so I the declaration:</p>
  
  <pre><code>xClass mysclass[] = new xClass[10];
  myclass[0] = new xClass();
  myclass[9] = new xClass();
  </code></pre>
  
  <p>However, I don't know if I will need 10. I may need 8 or 12 or any other number for that matter. I won't know until runtime. 
  Can I change the number of elements in an array on the fly? 
  If so, how?</p>
