    Do an internet search for the term "java varargs" for java specific info, or "programming ellipsis" for a more general description. Lots of info, for instance, the following link:
    Varargs

    That feature is called varargs, and it's a feature introduced in Java 5. It means that function can receive multiple String arguments:
    The parameter that gets the ... must be the last in the method signature.
    public void myMethod(String... strings){
    for(String whatever : strings)
    {

    }
