title: How do I skip over a String?
body: <p>This method prints out a text representation of a square or rectangle depending on what lengths the user enters. It prints out the correct dimensions however, how would I make it hollow?    </p>
  
  <pre><code>public String printShape() {
      String message = "";
      for (int i = 0; i &lt; length; i++) {
          for (int j = 0; j &lt; width; j++)
              message += "* ";
          message += "\n";
      }
      return message;
  }
  </code></pre>
