It will tell you more than you wanted to know. Follow links to Sun's
documentation, and believe it or not, read the source.
It is far shorter than the English language explanations of how it
works.

bburt083,
all collection implementations implement Serializable, so if the
elements in them are Serializable, too, you can write a collection to
disk using ObjectOutputStream plus FileOutputStream.
For an example of using OOS, you could look at this lesson :
