title: Is there any alternative to Java properties for keeping tree-like data?
body: <p>I have 3 item data that I should keep on remote PC. Let it be: ID, login, password.
  If there're only 2 items, Java property will suit me great, but I have some sort of tree. It is impossible to install any DB on that machine, so the variant with DB usage is declined at once.</p>
  
  <p>Do we have any alternative to Java properties to solve this task?</p>
  
  <p>P.S> Almost forgot, there's only JRE on remote PC and I have no way to install JDK there.</p>
  
  <p>Thank you in advance for you help.</p>
