java – String … whats do String … mean

I want to figure out some java code

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

What is an operator?

Thank you. Sorry, some searches can't be found elsewhere

Solution

This is a varargs declaration

It says you can call the method with 0 or more string parameters as final parameters Substitute:

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

You can use

write("A","C");

So each string is a different parameter Then you can iterate over them, for example

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