Hi Payal,

Above code will give following error:

java.lang.Error: Unresolved compilation problem:

Cannot make a static reference to the non-static field MyArg

If you run following code you will get following output.

public class Arg{

public static void main(String argv[]){

for (int i=0; i < argv.length; i++)

{

System.out.println(argv[1]);

}

}

}

Output will be:

there

there
