If you know what the Java programming language and runtime are, then you can understand Java beans.

Serialization is the ability to easily store the state of an Object in memory onto some long-term medium (on a hard drive, for example). Basically, the Serializable interface allows us to tell Java to turn our Object into a byte-stream. The Object could be a document that the user is working on, or a more complex data class which needs the ability to be saved to the hard drive. Using the Serializable interface (and related I/O methods), Java will do most of...
