title: serializing a list of objects into a file in java
body: <p>I have a list of around 20,000 object, which in turn have a very huge hierarchy. I need to dump the objects into a file, so that i can read it later anytime during my process. Now my problem is, I have worked on Java but not that much on serialization and i dont have that much of knowledge how to do that.</p>
  
  <p>In this case as far as i know, i need to use both Serialization ane De-Serialization. Can anyone please help. Also i can use any new API or normal Java Serialization.</p>
  
  <p>Regards.</p>
