What is the preferred way to write boolean expressions in Java

Question

I have always written my boolean expressions like this:

if (!isValid) {
  // code
}

But my new employer insists on the following style:

Answer 1

I just want to say I learned C twenty years ago in school and have moving onto Perl and Java and now C# which all have the same syntax and...

I think (!myvar) is the most popular

I think (myvar==false) is just fine too

in 20 years i have NEVER EVEN SEEN

(false==myvar) 

I think your boss is smoking something-- I'm sorry but I'd take this as a sign your boss is some kind of control freak or numbskull.

Answer 2

IMO the first one is much more readable while the second one more verbose.

I would surely go for the 1st one

Answer 3

It was discussed for C# several hours ago.

The false == isValid construct is a leftover from C-world, where compiler would allow you to do assignments in if statement. I believe Java compilers will warn you in such case.

Overall, second option is too verbose.
