java main() problem?

[harsha k]

class myclass
{
public static void main(String arg[])
{
}
}
when i execute program
javac myclass.java
then run program
java myclass
everything is ok here.But my confusion is that when we define main () method,we write it with parameterized method (String ar[]) and at the run time we are not giving any parameter.
or value.then how it is work actually. even there is not function overloading.

Good question, I cant even find the api that describes main.

Im guessing your either the argument is given null values internally, or main's function signature implements varargs, but since varargs are new to Java, I think the latter is more probable.

the main method is a special method, if u will like the .equals() method (not one to be over written but u understand) the array of string arguments that it takes as parameters is actually the lines that u write in the actual program. so the lines of code u write in ur programs is the parameters passed through the main method.
