Q on variable arity parameter :-)

[Peter Gade Christensen]

yeah sorry variable args ... The K&B book says variable args are defined like so ...pg 47 SCJP5

"Follow the type with an ellipsis (...) and a space and then the name of the array that will hold the parameters"

I did a couple of experiments - doesn't seem like the compiler holds us to one space between the ellipsis and the parameters -

    
String... args
String ... args
String     ...      args  
String <add multiple spaces here>  ...  <add multiple spaces here>   args  
  

All of these seem to work well - Any pointers to what is the correct syntax?

Thanks!!

Whitespace is not significant in Java except where it serves to delineate tokens. In this case, no whitespace is actually needed at all, so (String...args) is perfectly correct. But the convention is a single space after the dots.

Yes that's agreed , then K&B should not have added in the basic syntax.

The basic syntax should be :

<type>...<array-name>
