question about wrappers..

[Andres Gonzalez]

class G {
public static void main (String[] args) {
// System.out.print(Long.parseLong("11", 2)+", ");
//System.out.print(Long.parseLong("011", 8)+", ");
// System.out.print(Long.parseLong("11", 10)+", ");
System.out.print(Long.parseLong("11", 16));
}
}

the result (uncommenting all the lines) is:
3, 9, 11, 17
Can anyone explain to me why 17 is printed?
thx
I do understand the lines that are commented, but the last one I don't

hi
so u didn't understand that "why the last output number is 17?"
well, how did u understand the other output numbers? they r in some "radix" right? first is binary, second is octal, third is decimal and forth is?? - Hexadecimal (base 16).
base for,
binary is -2
octal is -8
decimal is - 10
hexadecimal is - 16
so the 11 in,
binary = 2*1 + 1 = 3
octal = 64*0 + 8*1 + 1 = 9
decimal = 10*1 + 1 = 11
hexadecimal = 16*1 +1 = 17
thats how we get 17.
did i address ur problem?
its just different radix systems...

maulin
