View source for More programming with Java

= This book is a work in progress =
This book is being written and is not yet completed. Feel free to dive in and start reading anyway. Of course all feedback is welcome by the [[Authors]].
= Introduction =
This book is a follow-up to our first book on Java, [[Programming with Java]]. It can be used for self-studies, or as course literature for a second Java course (a course which would follow an introductory Java course).

Regards from the authors: [[Authors#Rikard_Fr.C3.B6berg|Rikard Fröberg]] and [[Authors#Henrik_Sandklef|Henrik Sandklef]]

= Before reading this book =

== Intended audience ==
Any one with basic knowledge of Java and programming, who wants to learn a little more about Java and some slightly more advanced topics.
== Requirements ==
This book assumes you have knowledge of the Java programming language and some experience from writing programs using Java. If you feel that you need to freshen up your Java knowledge before starting with this book, we recommend our first Java book, [[Programming with Java]]. The chapters related to JDBC (database connectivity) require basic knowledge about SQL and SQLite. You can freshen up your SQL skills by reading our book [[Introduction to Databases]].

As with all our teaching materials, we are using the command line and the Bash shell in our examples and exercises. Therefore, we recommend that you freshen up also your bash skills, before using the material presented here. We recommend at least [[Bash-introduction]] but it doesn't hurt if you look a little at also the [[Bash_Programming]] materials.
