Java Serialize and DeSerialize | Json

I was trying to persist a complex object in java and re-use it later after re-running the program. Java supports traditional Serializable interface which is also cool. But it was rather looking for a better way to do it and I found this awesone API called json-io. You could also download the jar file from its maven repository, include it in the classpath and use it. I am writing a simple code to demonstrate it for my reference but you could always go to its site and learn more.

Well, I should mention this. I was trying to implement a desktop application which has some settings. The application should save its settings and perform according to them. The settings should persist, the next time the application is started. I could simply create a map, for the options, update the maps in run time and save them in a file on exit and reload from the same file.
