Student Resources: A bound-in access card to the password-protected Companion website is included with the purchase of a new copy of the textbook.

Visit to access the following students resources: Personalized Learning with My Programming Lab Through the power of practice and immediate personalized feedback, My Programming Lab helps students fully grasp the logic, semantics, and syntax of programming.

Java is fast, "Complies Once Run Forever" is the line which the language is famous for.

This combination of superb features alone make Java a great language for any programmer and entrepreneur, in building their applications.

For students, the system automatically detects errors in the logic and syntax of their code submissions and offers targeted hints that enable them to figure out what went wrong—and why.

Java is a powerful and versatile programming language. It is also an platform independent language, which mean you could run Java on any computer and OS which could handle its basic requirements.

Java is also very secure, it uses the encoded byte-code in compiling your source code.

The second part composes of 100 popular coding challenges, often used by companies in testing junior programmers.

Each challenge will have their solutions in PDF files attached to the lectures. You should have a look at the first part before embarking on the second.
