Syntax of Array as parameter in JDK 1.6

[Rahul Shilpakar]

Hi,

I am using jdk 6 compilation.
I have seen an example which has a method like follow

                 a class{
                                   methodX()
                                   {
                                               String[] say = {"hi", "by"};     [b]// LINE 1[/b]

                                               myMethod(say);
                                   }                                              

                                    myMethod(String... passedSay)                   [b]// LINE 2[/b]
                                    {
                                           for (String message : passedSay)
			System.out.println(message);
                                     }
                           } // class close

My Questions are:
1) Why jdk 6 uses notation '...' insted of '[]' notation at LINE 2 ? Is there any particular significance or reason?
2) What is advantage of this '...' sign.
3) If i make same notation at LINE 1 its giving me compilation error. Why? Does it used for passing parameter notation?


I don't have have any idea about that notation. Please tell me about it. I also run above program and it compiles fine.
I also saw this notation in one Question of SCJP 1.6 Version.

The ... notation denotes 'varargs'. You are passing some number of Strings into the method,
