String[] arg and String... args

[mahendra.athneria]

Hi All,

As in Java 1.5 and lateral we can use String... arg instead of String [] args in

public static void main() method.

so it means if we can use both of them as a interchangebly.

is this true? if yes the what would be the answer of below question?

logIt(”log message 1 “);
logIt(”log message2”,”log message3”);
logIt(”log message4”, “log message5”, “log message6);
Which declaration satisfies this requirement?

A. public void logIt(String * msgs)
B. public void logIt(String [] msgs)
C. public void logIt(String... msgs)
D. public void logIt(String msg1, String msg2, String msg3)

Answer: ??

C, obviously. You should know why - if you get this question. If you don't, post. :)

Doing some searching, I found the following information...

Passing Information to a Method or a Constructor (see "Arbitrary Number of Arguments" section)
Java Varargs
Java Tips - Using the VarArgs Language Feature

So the name of this beast (Object... arguments) is called "varargs".
