The interface Serializable indicates that you can write an object out to a file or byte stream. Java uses this to move objects around between systems, store objects in files and retrieve them later, etc. Take a look at the package - classes like ObjectInputStream and ObjectOutputStream. Pretty cool technology.

Hi, is a tag interface which suggests that the state of the object is saved.You use it in distributed computing like RMI, when you have to send information across machines.
Hope this helps,
