I've just acknowledged dot notation for method declaration with multiple arguments
like this:
public function getURLs(URL... urls){
for(int i = 0; i < urls.length; i++){
// walk through array of arguments
}
}
And using like this
getURLs(url1, url2, url3);
where those method arguments are converted implicitly into URL[] urls
Yes, that is how it works. The arguments are automatically put into an array. The argument "urls" behaves like a URL[]
. Varargs are documented here . They were introduced in Java 1.5, so, are available in J2SE 1.5+, and all of Android since it supports Java 1.5+ language features. No version of JavaME/J2ME supports it.
The syntax was introduced in Java 5 and is called varargs:
