An Introduction to Object-Oriented Programming with Java provides an accessible and thorough introduction to the basics of programming in java. This much-anticipated revision continues its emphasis on object-oriented programming. Objects are used early so students begin thinking in an object-oriented way, then later Wu teaches students to define their own classes.

In the third edition, the author has eliminated the author-written classes, so students get accustomed to using the standard java libraries.

In the new update, the author has included the Scanner Class for input, a new feature of Java 1.5.

Also new is the use of smaller complete code examples to enhance student learning. The larger sample development programs are continued in this edition, giving students an opportunity to walk incrementally walk through program design, learning the fundamentals of software engineering. The number and variety of examples makes this a student-friendly text that teaches by showing.

Object diagrams continue to be an important element of Wu's approach. The consistent, visual approach assists students in understanding concepts.
