Java I/O

Elliotte Rusty Harold is a noted writer and programmer, both on and off the Internet. He started by writing FAQ lists for the Macintosh newsgroups on Usenet, and has since branched out into books, Web sites, and newsletters. He's currently fascinated by Java, which is beginning to consume his life. His Cafe Au Lait Web site at http://sunsite.unc.edu/javafaq/ is one of the most popular independent Java sites on the Net. Elliotte resides in New York City with his wife Beth and cats Charm (named after the quark) and Marjorie (named after his mother-in-law). When not writing about Java, he enjoys genealogy, mathematics, and quantum mechanics, and has been known to try to incorporate these subjects into his computer books (when he can slip them past his editors). So far he hasn't been able to, but he suspects that a short, last-minute biography might not be inspected as closely as the rest of a manuscript. His other books include The Java Developer's Resource (Prentice Hall), Java Network Programming (O'Reilly), Java Secrets (IDG Books), and JavaBeans (IDG Books)
