• Key Concepts: 
  A serializable object is an object in the Java Application Server (BC-JAS) that can be converted into a stream of bytes and stored in a file or other storage medium. This allows the object to be transferred between different systems or applications, and also allows for the object to be restored to its original state. 
  
  How to use it: 
  In order to use a serializable object, it must first be declared as such. This is done by adding the keyword “serializable” to the class definition. Once this is done, the object can then be saved and restored using the Java Object Serialization API. 
  
  Tips & Tricks: 
  When declaring a serializable object, it is important to ensure that all of its fields are also declared as serializable. If any of the fields are not declared as such, then they will not be saved or restored when the object is serialized. 
  
  Related Information: 
  The Java Object Serialization API provides a number of methods for saving and restoring serializable objects. These include writeObject(), readObject(), and writeExternal(). Additionally, there are a number of third-party libraries available that provide additional functionality for working with serializable objects.
