Hello,

You would have been better off working a little bit more on your code
before posting it on a newsgroup. By the way :

Java is case sensitive (java.io not Java.io) (and as a convention, class
names should be capitalized while variables should not).

You need to define precisely the scope of your blocks (classes, methods,
control structures ...) with "{}" characters.

Java is not self-correcting, make sure no letters are missing (main not
man).

Dots should not be added randomly to your code, they have a precise
signification related to object-oriented programming.

But well, here is the working code :

import java.io.*;
public class Commander {
public static void main(String[]args) throws IOException {
BufferedReader in =
new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter your code :");
try {
int code = Integer.parseInt(in.readLine());
switch(code) {
case 1:
System.out.println("One");
break;
case 2:
System.out.println("Two");
break;
case 3:
System.out.println("Three");
break;
case 4:
System.out.println("Four");
break;
case 5:
System.out.println("Five");
break;
case 6:
System.out.println("Six");
break;
default:
System.out.println("Whatever");
}
} catch (NumberFormatException exception) {
System.out.println("You did not enter a number");
}
}
}

Good luck with java ... and buy a good book on the subject (Learning
Java; Patrick Niemeyer & Jonathan Kundsen; O'Reilly & Associates, Inc;
ISBN 1-56592-718-4 for example), it helps.
