String ... <varname> whats String ... means

Question

I am trying to figure out some kind of Java code. I came across something that I had not seen in the method header before

private static object [] methodName(NodeList nodes, String... Names) 

What is an operator ... ?

Thank you and sorry, some searches did not find it elsewhere

Answer 1

This is a varargs ad.

This suggests that you can call this method with 0 or more String arguments as final arguments. Instead:

 write(new String[]{"A","B","C"}); 

you can use

 write("A", "B", "C"); 

So each line is a different argument. Then you can iterate over them, for example.

 public void write(String... records) { for (String record: records) System.out.println(record); }

Answer 2

... stands for "varargs", meaning you can provide an arbitrary number of String arguments. See http://download.oracle.com/javase/1.5.0/docs/guide/language/varargs.html .
