Beginning Java Programming

A comprehensive Java guide, with samples, exercises, case
studies, and step-by-step instruction

Beginning Java Programming: The Object Oriented Approach
is a straightforward resource for getting started with one of the
world's most enduringly popular programming languages. Based on
classes taught by the authors, the book starts with the basics and
gradually builds into more advanced concepts. The approach utilizes
an integrated development environment that allows readers to
immediately apply what they learn, and includes step-by-step
instruction with plenty of sample programs. Each chapter contains
exercises based on real-world business and educational scenarios,
and the final chapter uses case studies to combine several concepts
and put readers' new skills to the test.

Beginning Java Programming: The Object Oriented Approach
provides both the information and the tools beginners need to
develop Java skills, from the general concepts of object-oriented
programming. Learn to:

• Understand the Java language and object-oriented concept
  implementation

• Use Java to access and manipulate external data

• Make applications accessible to users with GUIs

• Streamline workflow with object-oriented patterns

The book is geared for those who want to use Java in an applied
environment while learning at the same time. Useful as either a
course text or a stand-alone self-study program, Beginning Java
Programming is a thorough, comprehensive guide.
