Scanner input error

I want to make a very simple program that allows the user to enter a key/character and have the corresponding unicode value returned. The problem is that I receive an error after the input of any character.

Here is the code:

import java.util.Scanner;

public class KeyMap

{

public static void main (String args[])

{

int number; //the future unicode value.

System.out.print ("Enter the key you want the unicode number of: ");

Scanner scan = new Scanner (System.in);

number = scan.nextInt();

char key = (char)number;

System.out.print ("The number for key " + key + " is " + number);

}

}

And I get this error in the run log after the character is entered:

Exception in thread "main" java.util.InputMismatchException

at java.util.Scanner.throwFor(Scanner.java:819)

at java.util.Scanner.next(Scanner.java:1431)

at java.util.Scanner.nextInt(Scanner.java:2040)

at java.util.Scanner.nextInt(Scanner.java:2000)

at KeyMap.main(KeyMap.java:11)

KeyMap has exited with status 1.

Thanks for any help!
