[compilation error] debugging this error message "Object() in java.lang.Object cannot be applied to"

Hi,

I have a class called Device that instantiates another class DbMoney
in this manner:

===
return new DbMoney( money, hardware.getName() );
===

1) Both are in the same package, i.e. my.IMoney & my.Device

2) When I compile them, javac complains with the error:

Object() in java.lang.Object cannot be applied to (my.IMoney,
java.lang.String)
return new DbMoney( money, hardware.getName() )
^

Q) My arguments to the DbMoney constructor match that of its declared
method parameters. So that can't be the problem. What am I doing
wrong ?

G'day. Please note that starting a post's

I suggest not to do that, so everyone can see
the entire subject line.

Do they? Your code snippets do not support
that, or more accurately, if we had an SSCCE*,
we could confirm that for ourselves.

I am not sure, but if you supply an
SSCCE of your current code, that shows
the same compilation error, I might be
able to assist further.

* For more info. on the SSCCE, see..

Or better yet. Ignore the entire issue, and whatever way GG happens to be
broken today. Stick to well-established Usenet conventions. If GG can't get
its act together then so much the worse for Google, its users, and its
advertising income.

I.e. bugger Google.

Andrew's advice to reduce this to an SCCCCE is good, you should follow it.

But, just as a guess, it sounds as if my.DbMoney has no constructors -- have
you inadvertently turned your would-be constructor into a normal method by
giving it a return type ?
