title: How can a string array store arrays?
body: <p>I know that the array declaration below is correct:</p>
  
  <pre><code>String[][] arrayNew={{"teresa","human","jennifer"},{"18","20"},{"nothing"}};
  </code></pre>
  
  <p>I understand that <code>String</code> and <code>array</code> are two different object types in java.So how come the <code>string array arrayNew</code> is successfully storing three different arrays in it.
  An <code>int</code> array can not store <code>doubles</code>but how come a <code>string array</code> is able to store <code>arrays</code>?</p>
