The following example explains how to use varargs.
Import to know is that the varargs paramers must come last in the parameter list.

public class VarArgsExample {
    String concat(String... words)
    {
        String sentence = "";
        for(int i=0; i<words.length; i++) 
        {
            sentence += words[i] +" ";
        }
        return sentence.trim();
    }

    public static void main(String args[])
    {
        VarArgsExample va = new VarArgsExample();
        String aSentence = null;

        aSentence = va.concat("hello","world","!");
        System.out.println(aSentence);
    }
}

This example would print:

hello world !
