This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
You should recognize that a numeric literal that begins with 0 is octal (base 8), and one that begins with 0x is hexadecimal (base 16). In hexadecimal, the letters a, b, c, d, e, and f are used to represent base-10 values 10, 11, 12, 13, 14, and 15 respectively.
(Note: The "x" can be either upper or lowercase -- just like an "L" to denote long, an "s" to denote short, or an "e" to denote exponent.)

Thanks Chris , Marc. final query on this topic, do these kind of 'otherwise calculator-calculations' [ powers of 16 multiplied and added with 2 digit numbers ] a regular feature in the exams ?
