Input from keyboard

Question

Hey everyone, I'm new to java and am having some problems.
I'm trying to make a simple program that reads a numeric value
entered from the keyboard, and then adds or subtracts it from
another variable for the final output. Ive gotten input to work with
chars, but I need int. Any help would be much appreciated.

// The "Input" class.
import java.io.*;
public class Input
    public static void main (String [] args)
        try
            System.out.print ("Enter Int: ");
            BufferedReader input = new BufferedReader (
                    new InputStreamReader (System.in));
            String userInput = input.readLine ();
            int intValue = Integer.parseInt (userInput);
            System.out.println (intValue);
        catch (NumberFormatException ex)
            System.err.println (ex.getMessage ());
        catch (IOException io)
            System.err.println (io.getMessage ());
    } // main method
} // Input class
