title: The matrix doesn't print correctly
body: <p>I've been trying to display a matrix <code>3xn</code>, <code>n</code> being determined by the lenghth of a phrase introduce.
  The problem itself is that instead of displaying a <code>3x2</code> matrix for abcdef it like this

  <p>I used the standard way for printing it with a <code>for</code> for the rows and another one inside for the colums:</p>
  <pre class="lang-java prettyprint-override"><code>for (int i = 0; i &lt; v1idk.length; i++) {
      for (int j = 0; j &lt; v1idk.length; j++) {
          System.err.println(Arrays.toString(v1idk[i])
                  + Arrays.toString(v1idk[j]));
      }
  </code></pre>
  <p><code>v1idk</code> being a <code>int</code> variable. Does it has to do anything with the <code>System.err.println</code>, or does there's no problem in this bit and I should search in other place?</p>
  <p>If it was necessary here is the rest of the <a href="https://i.stack.imgur.com/ItLOU.png" rel="nofollow noreferrer">code</a></p>
