I'm trying to write a Java Program, but I don't know what I'm doing wrong?

[diva]

I am trying to implement a Java program that displays the following text menu:

0-Exit
1-Compute the sum of some numbers
2-Compute the product of some numbers

Here is the code. What am I doing wrong?? When I try to compile it, I get several error messages.

import java.io.*;

public class p2
{

private static BufferedReader stdin =
new BufferedReader( new InputStreamReader( System.in ) );


public static void main ( String [] args ) throws IOException
{

System.out.println( "0-Exit" );
System.out.println( "1-Compute the sum of some numbers" );
System.out.println( "2-Compute the product of some numbers" );


String input = stdin.readLine();


switch(input)
{
case "0":
break;
case "1":

break;
case "2":

break;
default:
System.out.println( "Invalid Selection" );
break;
}

System.out.println( "Bye Bye" );

}

}
