title: How to handle an object array of Object Arrays
body: <p>I have this code:</p>
  
  <pre><code>Object [] array=new Object array [5];
  array[0]= new Object[3];
  array[1]=new Object [10];
  array[2]=new Object [7];
  ...
  </code></pre>
  
  <p>How can I access the 5th element of array[1].
  If it was a 2D array I would say:</p>
  
  <pre><code>Object o=array [1][5];
  </code></pre>
  
  <p>but I don't want 2D array because I don't want to waste memory since the size varies from array to array.</p>
  
  <p>It would be great if someone could answer me this question..</p>
  
  <p>Btw I don't want to use vectors etc...</p>
  
  <p>Thank you</p>
