Java math challenge

What should be printed?

 int result = 0; result = result + (null != null ? 3 : 2); result += (1 & 2) == 1 ? 2 : 3; result += 1e5; result += 1e2; System.out.println(result);

10106.0, I think. Because:

null != null == true 1 & 2 == 0

No, you made a little mistake, null == null always true, therefore null != null should always be false.

Ah! You're right. 100105, then. (I also mistakenly added a .0 and lost a power of 10.)

By the way, if you put java after the backticks on your code box, it applies Java syntax highlighting!

This:

will produce

System.out.println(1 + 2 == 3);

...while this:

will produce

System.out.println(1 + 2 == 3);

This works with JavaScript (js), Python (python), and lots of other languages, as well.

Wow, thank you! I didn't know it.
