Hi

Please tell me in details about Command Line Argument with program.

I'd ask Google for some examples, then if there were any questions about what was found, copy and paste the code here with your questions.

//Command Line Argument

class Prg1
{
public static void main(String[] args)
{
for(int i=0;i<args.length;i++)
{
System.out.println(args[i]);
}
}
}

What are your questions?
Have you compiled and executed the program?
What did you put on the command line when you executed the program?
What is printed out?
