Introduction to Programming Using Java

Introduction to Programming Using Java is a free introductory computer programming
textbook that uses Java as the language of instruction. It is suitable for use in an introductory programming course and for people who are trying to learn programming on their own. There are no prerequisites beyond a general familiarity with the ideas of computers and programs. There is enough material for a full year of college-level programming. Chapters 1 through 7 can be used as a textbook in a one-semester college-level course or in a year-long high school
course.
This version of the book covers “Java 5.0”. It also works well with later versions of Java. (While Java 5.0 introduced major new features that need to be covered in an introductory programming course, Java 6.0 and the upcoming Java 7.0 do not.) Many of the examples in the book use features that were not present before Java 5.0. Note that Java applets appear throughout the pages of the on-line version of this book. Many of those applets will be non-functional in Web browsers that do not support Java 5.0.
