Reading commands from the command line

Question

Ok I've read quite a bit about streams, and I get the gist that you are suppose to open up a "stream," whether it from a file or from something else, and then you have to do all sorts of stuff to it like activate it or something, or whatever. But all I want to do is take an input from the command line, for example my name, and have it output "Hi [name]." I could swear I've done this before with a simple command like
System.in.read() or something like that, but I read up on it and read is not a method that does that? So how does one just do a simple command line input into a variable...for what I want to do is control movement on a maze. If somebody can direct me to some documentation I would be happy as well. Thank you

btw - "deadseasquirrels" - like the name. Have another program;-
import java.io.*;
import java.util.Random;
public class Do_Writing {
   public static void main( String args[] ) throws IOException {
   BufferedReader in = new BufferedReader
                       (new InputStreamReader(System.in));
   Random rand = new Random();
   int i = 1+ rand.nextInt(10);
   String s1;
   System.out.println("Guess a number between 1 and 10");
      try {
         while ((s1 = in.readLine() ) != null) {
            // if( ... I'll leave the rest to you to figure out
            // when they get it right don't forget to include;-
            System.exit(0);
            in.close();
   catch (IOException ignore) { }                     
}
