Introduction to Computer Science using Java

Bradley Kjell, Central Connecticut State University

This is a course in Java programming for beginners. It covers the fundamentals of programming, roughly the same material that is covered in a beginning programming course in a university or in a high school AP Computer Science course.

For maximum benefit, go though these ../Java5/Notes interactively, thinking about and answering the question at the bottom of each page. There are about 20 pages per chapter. If you spend about 3 minutes per page each chapter will take about 60 minutes, or longer if you copy and run some of the programs. If you are a beginning programmer, plan on spending more than a month with this.

These Notes assume that you have a recent version of Java, available from Oracle, Inc. at http://www.oracle.com/technetwork/java/index.html and a text editor such as Notepad. Compiling and running programs is done from the command line interface. You may use more sophisticated environments, as well.
