Requesting user input from UNIX command window

Question

New to this forum, and relatively new to Java......question for you......
Currently, I am able to request a .txt file from a user in my unix command window by having them type in the following command:
java Game (nameOfTextFile).txt
with the following code:
public class Game {
public static void main(String[ ] args) {
try{
reader = args[0];
catch(Exception g){
System.out.println(g);
where 'reader' holds the .txt file.
What I would like to do is as soon as the user types in the command:
java Game
it gives them the line:
"Please type the file to be input"
and at this point they type in:
(nameOfTextFile).txt
and then I can start working with the text file.
Any ideas?
Thanks

public class Game {
public static void main(String[ ] args) {
try{
reader = args[0];
catch(Exception g){
System.out.println(g);
}This class will not compile. The variable 'reader' is not declared anywhere.
You could create a shell program. When the user enters the name of the shell program at the command prompt, it gives them the prompt to enter the file to be input. And then from within the shell program you call the java program with the name of the file.
