This book is a creation of the Knowledge Collection and Contribution
Initiatives by the Department of Computer Engineering, Chulalongkorn
To my parents, who have always committed
to providing the best education for me.
Computer programming skills are currently must-have skills for every
university graduate in any fields of Science and Engineering. This book
is aimed to be a textbook suitable to be used in a first programming
course for university-level students. The primary goals of this book are to
introduce students to creating computer programs to solve problems
with high-level languages. Programming concepts appearing in modern
programming languages are presented through writing Java programs.
Java is selected as the language of choice due to its relatively simple
grammars. It is also a good choice for introducing students to the concept
of object-oriented programming which is one of the most popular
paradigms in the current days. Furthermore, Java is one of the most
widely-adopted programming languages by the industries.
This book is developed from the class notes that the author wrote for the
introductory computer programming course offered to students in the
International School of Engineering, Chulalongkorn University. The
writing style and the content organization of this book is designed to be
straight-forward. Details not crucial to understanding the main materials
presented in their related sections are usually omitted in order to relieve
the readers from worrying about having to know 'too much'. References
for further readings will be given along the way.
The author hopes that this book would introduce readers to the joy of
creating computer programs and, with examples given in this book,
writing computer programs would appear to be more realizable,
especially for beginners with absolutely no programming background.
