A Primer on Java
A Primer on Java
Second Edition
About the Book
A gentle introduction to the basics of Java. No prior programming experience is necessary to read this text. My purpose was to write an easy but non-verbose introduction to the language.
The book however is not intended as a reference work or for a full time Java programmer since it does not have an exaustive topic coverage.
