Uni project methods & negative numbers arrghhh

Question

Hi there i have written a program for uni it creates a random number & gives the user 3 guesses at getting the number before giving them a message saying they have lost and revealing the actual number. So far so good . I managed to get this working but the next part of the project requires me to use a method which gives the user a message giving them a hint. The hint tells them whether they are hot, warm, cold etc.
I have tried to implement this in my program using this code but its not working im getting 3 messages like
ERROR: 'class' or 'interface expected
Also i think my use of negative numbers is wrong i can remember someone telling me you have to change the negative number into a positive before u can manipulate it or something like that.
Anyway any help would be greatly appreciated.

Yep, faulty as designed.
try this:public static String howClose(int usersguessint, int randomnumber) {
          int difference;
          difference = randomnumber - usersguessint; // <---
          if ((difference < 2) && (difference > -2)) {
               return "hot";
          if ((difference < 3) && (difference > -3)) {
               return "warm";
          return "cold";
     }// end method
