Octal numbers don't have digits 8 & 9. Their range is from 0 until 7!
Any number prefixed w/ leading 0(s) is interpreted as an octal literal!

A quick example...
Octal literal 0400 = decimal literal 256:

int s = 000400;
println(s);
exit();

Hummm octal wtf!! I want decimal ints. Thanks for explaining.  I was getting a video time code string like "12:43:34:20", spliting and converting to ints to do some math... When I had, for instance, "00:10:10:09" i felt in this octal world with "unexpected token 9" error, i guess i need to check for a leading zero... can it be, kind of,  casted? Thanks.

Thanks, i have tried this, but unsuccessfully, now, after your example I found my mistake somewhere else.

Funny how some topics come close in time, even if from unrelated paths.

What do I need octal for...   Thanks guys. I sticked to strings to pass time code values.
