title: Consecutive run programming
body: <p>I want to show the sentence "Hello" that is after finish process of <code>main</code> method:</p>
  
  <ol>
  <li>input name and it's correct, </li>
  <li>ask age, and </li>
  <li>correct going to sentence "booting up"</li>
  </ol>
  
  <p>which means I want to run method consecutively.</p>
