int x=4;
double y= 841/++x%10/2+15/(x++/3.0);
System.out.println("y = " + y);
why is the answer 13? why is ++x = 6 and x++ = 7?? Thanks a lot. I'm so new to Java. Isn't it x=4 , ++x=5 x++=6 ? how is it 6 and 7.

1You should be able to crack this puzzle yourself if you arm yourself with Java's operator precedence table. (Note that you expression would be undefined in C and C++). – Bathsheba Dec 09 '15 at 12:51

The duplicate addresses only part of the puzzle. There are other things in there too: type promotion being one of them. – Bathsheba Dec 09 '15 at 12:55

i really don't understand how a variable changed from 4 to 6... – StupidProgrammingStudent Dec 09 '15 at 13:04

1Because that's what ++x and x++ do. – Bathsheba Dec 09 '15 at 13:05

It would be better if you read the duplicate carefully. – Bathsheba Dec 09 '15 at 13:14
