title: Cannot split input from `Scanner`
body: <pre class="lang-java prettyprint-override"><code>String command = scanner.next();
  String[] split = command.split(&quot; &quot;);
  System.out.println(split.length); 
  </code></pre>
  <p>Hello, anyone knows why it gives me the length 1 back when I insert <code>&quot;a b c d e f g h i&quot;</code> ?</p>
