struts beans

[Harshani Wickramarathna]

Hi,
I've got this code from tutorial. But I couldn't try it because it says the method randomString undefined. Can you please help me on this.

package coreservlets;
import java.util.*;
public class SuggestionUtils {
private static String[] suggestedAddresses =
{ "[e-mail]",
"[e-mail]",
"[e-mail]",
"[e-mail]"};
private static String chars =
"abcdefghijklmnopqrstuvwxyz0123456789#@$%^&*?!";
public static SuggestionBean getSuggestionBean() {
String address = randomString(suggestedAddresses);
String password = randomString(chars, 8);
return(new SuggestionBean(address, password));
}
}

The method 'randomString' is in the same class. Tutorial may haven't attached its codes
