Parameter naming: filename or fileName?

Question

I try to be grammatically correct in my naming*. I\'ve always used filename instead of fileName. The java convention also seems to use this, but

Answer 1

I think the answers here are spanning two issues.

• 'FileName' vs 'Filename' (should 'name' be a separate word)

  and

• 'fileName' vs 'FileName' (should first character be lower case).

In most cases, I prefer to treat this word as a single whole word 'filename'. I also prefer starting variables/methods with lower case for easier code completion menu navigation.

I guess the issue of camel case is here too which I think should be used to distinguish multi-word names.
