Essentials of the JavaTM Programming
Language: A Hands-On Guide, Part 2
by Monica Pawlan
[CONTENTS] [NEXT>>]
This series of lessons builds on the material presented in JavaTM
Programming Language Basics, Part 1, which introduced
applications, applets, and servlets; simple file and database access
operations; and remote method invocation (RMI).
The lessons and code examples for Part 2 are somewhat more
complex. They walk you through network communications, building
a user interface using more components, data encryption and
decryption (pseudo code only), grouping multiple data elements
into one object (collections), and internationalizing a program. Part
2 concludes with some object-oriented programming concepts.
