Why this code is giving ERROR

Question

int a=028;
System.out.println (a);

OUTPUT: error

Answer 1

Pradeep, Because any number starting with "0" is considered to be an octal value, and there is no digit above 7 in octal notation. In octal, 030 is next after 027.

If you try and observe you may understand, try 027 its working but not 028 because of above reason.

Answer 2

Pradeep, this is because you try to save large integer like 028, try with 28 its working.
