command line

[Zahra Vir]

Can someone help explain the concept of using the arg thingy in
public static void main (String args[])

so far i know that args can be named anything and that u can use it to get specific words ???

can someone elaborate a bit or provide some sort of example for this

thanks

Suspect this has been answered here before but here's a start for you.

args is just a variable name...you could call it any legal identifier, it's simply the name of our String array.

public class CommandLineExample {
 
   public static void main(String[] anyoldvar) {

      for(int i=0;i<anyoldvar.length;i++){
//this just gets the arguments passed in and writes them out
System.out.println(anyoldvar[i]);
      }
   }
}

After compiling, run this code from the command line with the "args" separated by a space, like this.

java CommandLineExample firstval secondval thirdval

Hope that helps!
