When JVM runs the class file then JVM looks for that particular signature.
[code=java]void main(String [])[/code]
Actually your mail function will never get call and your program never gets started.

Hi
It will depend on your mathod what it accepts and in which squence of data Types. Your question is very vast. post your method so that we can more clerify it.

Which method do you mean? If it's the main method
[CODE=java]public static void main(String[] args)[/CODE]then you won't be able to run it without the String array. However, you don't have to give it any arguments.

If you have a simple "Hello World" Program, it would look like this:
[CODE=java]
public class HelloWorld {
public static void main(String[] args) {
System.out.prin tln("Hello World!\n");
}
}
[/CODE]You would compile it with

javac HelloWorld.java

and run it with

java HelloWorld

However, running

java HelloWorld These are arguments

will result in the same - your program will have the array {"These", "are", "arguments" }, but it just doesn't care about it.

Any other function only can have a String array as arguments, if you define it so. (Which you will only do, if you need it.)

Hi,


My method is

public static void main(String args);

What happens in this case?

That is not the method signature (and name) the jvm is looking for so your class
can not be run as the starting point of your program.

Try it and see what happens. Don't you have the JDK installed.
