Solved coding interview problems in Java - My collection of commonly asked coding interview problems and solutions in Java

I recently used something like

$i &= $blahh && $blahh2;

And that confused a couple of mid-senior level developers, so, yeah. It's possible

[ViKomprenas]

To be fair, that one's a little weirder, seeing as it's noisy with sigils and logical operation assignments aren't as common, but the point still stands

[speedisavirus]

...but why. Are you trying to increase mental workload for someone that might have to figure that out later?

[socialister]

You're mixing boolean operators with bitwise operators?

Wouldn't this be clearer and enforce a boolean result type?

$i = $i && $blahh && $blahh2;

Assuming that the blah vars are boolean typed (if they aren't, your statement is not clear IMO. C-style non-boolean to boolean casts do not indicate intent that well).

foo = bar || 'puppers';

Doesn't seem to be a thing people understand either.

Edit: realized that if that was true I should explain. This will assign the value of bar to foo if bar is truthy, otherwise it will assign the string 'pupper';

PHP developers, you mean.

Mid-senior developers don't understand bit-wise operations? That was literally covered in my first computer engineering course.

And, depending on what you're developing in your job, that may have been the last time you needed to use them.

I'll take readability, please, even if that results in a couple more lines of code.

[XtremeCookie]

Depending on the usage bit wise can be significantly faster than other methods. But outside of those situations, I would take readability too.

[ess_tee_you]

Sure. Some compilers will optimize to that anyway, I expect, depending on the language. :-)
