title: Array length in a multidimensional array java
body: <p>I'm having difficulties understanding why once i declare a multidimensional array like : </p>
  
  <pre><code>int t2[][] = new int[5][10] ;
  </code></pre>
  
  <p>I can still change the length of the arrays like so : </p>
  
  <pre><code>t2[0] = new int[12];
  </code></pre>
  
  <p>I thought once we declare the array to be a certain length we can't change it. So how is it possible here ? </p>
