Why does 012 % 10 = 0 in Java?

Question

I am trying following program.

int var = 012;
int result = var % 10;

output:

result = 0

I am not able to understand why java is not able to consider 012 as 12.

Because 012 is an octal number. See duplicate link. – rghome Jun 12 '15 at 14:33 — rghome, Jun 12 '15 at 14:33

12

In Java, integer literals that start with 0 are interpreted as octal numbers.

So, 012 is the number 1 x 8 + 2 = 10 (in decimal), not 12 (decimal).

012 % 10 == 10 % 10 == 0
