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 java.io package - classes like ObjectInputStream and ObjectOutputStream. Pretty cool technology. Bill
