User I/O loop question

[Sudz28]

Hi! I'm trying to write a program that solicits the user for input and then asks them if they wish to run it again (y/n). I can't quite figure out how to work the loop though with the y/n response. Here is what I was trying to do, but obviously I'm having a problem:

import java.io.*;
import java.util.*;

public class LoopTest
{

// Begin Main

public static void main(String[] args) throws IOException
{
char response = 'y';
while (response == 'y')
{
Scanner stdin = new Scanner(System.in);
System.out.println("Please enter number of events to simulate: ");
int N = stdin.nextInt();
System.out.println("Please enter the probability percentage for an arrival: ");
double P = stdin.nextDouble();
System.out.println("You wanted " + N + " events tested.");
System.out.println("You chose a " + P + "% probability for an arrival");
System.out.println("Would you like to try again?(y/n) ");
response = stdin.nextChar();
} // end Main
}
}

I'm getting an error because there is no nextChar method this can use; but I couldn't figure out how to do it using a String for response - am I missing something very basic/easy?
Thanks!

Thanks much for your help! That's actually very close to what I started out trying to do (using 'String reponse = "y";'), but I couldn't get the test case (the 'while') to work right so that's why I started trying to us char instead. I appreciate your input, and will double-check the api specs again. I have to admit that I go there quite often in instances like these, but usually I end up more confused :-)
Cheers!
