title: java properties files, using a key as another keys value, is this possible
body: <p>I would like to know if there is any way to use a key as another key's value in .properties files. </p>
  
  <p>For example is this possible, or is there any other way to achieve something similar to this?</p>
  
  <pre><code>key = another_key
  
  app.name=Stack Over Flow  
  app.title.welcome=Welcome to {app.name} 
  </code></pre>
  
  <p>so when i get the value of <code>app.title.welcome</code> it should be "<code>Welcome to Stack Over Flow</code>"</p>
