Java Error - java: class, interface, or enum expected -

would able advise me on causing java error in basic program trying write?

the error received says: error:(27, 1) java: class, interface, or enum expected

here code below package name.

import java.util.scanner;  public class main {     public static void main(string[] args)     {         scanner kbd = new scanner(system.in);         string s = "";         boolean isok = true;          while (isok)         {             system.out.print("key in numeric string (enter minus sign - quit): ");             s = kbd.nextline();             char c = s.charat(0);             if (c == '-')             {                 isok = false;                 system.out.print("you have quit program.");                 return;             }         }         }     } } 

you have closing brace

remove last '}'.

i tested code manually, simple, works fine.
