title: String [][] clarification
body: <p>I'm just asking about this instruction:</p>
  
  <pre><code>String[][] s = new String[2][2];
  </code></pre>
  
  <p>If i create this variable "s", will i create a string table with 2 lines and 2 columns ?
  Or 2 tables with 2 elements? 
  Thank you for this clarification.</p>
