Let's see an example in octal:
234 (octal)
2 should be multiplied by 8^2 (8 square; right now, I don't remember the syntax in Java). 2 should be multiplied by 8, and 4, simply by 1.
A shortcut, which sort of bypasses the use of powers, is:
(2 * 8 + 3) * 8 + 4
IOW: repeatedly multiply by 8, and add the next digit.
For hexadecimal, you would have to convert "A" to 10... "F" to 15, first, and then apply the same algorithm (multiplying by 16, of course).
