public static int parseInt(String s,
throws NumberFormatException

output: 411787

I could not understand the output. i.e.
1.How to decide the range of radix.( in between Character.MIN_RADIX and Character.MAX_RADIX. given in api)
2.How can we decide what would be printed, if we take a radix 19 or 24.
3.what cab be allowed values for String argument if we take a radix, say 34.

Character.MIN_RADIX = 2 and Character.MAX_RADIX = 36

If you set the radix to the max i.e. 36, then the resulting Number system would have this sequence of digits (you can say it as the primary parts of a number system or something like 0-9 in decimal system are the basic parts which can be combined to form say one hundred and fifty as 150)

0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ

And suppose you take radix as 27, then the allowed values will be

0123456789ABCDEFGHIJKLMNOPQ

Ohhhhh my god, It will surely out of course, this is not SCJP question, this is Mathematics question. If they want to ask such question than there should be another exam like SCJP Maths-310-M65.

I was born a mutant and I have 18 fingers in each hand, so for me this is second nature (unnature.) I pity you, mortals.
