question about java/netbeans?

here is a little chunk of code:

1import java.util.*;

2

3public class Skill {

4 private int rat;//skill rating

5 private String spec;//specialization

6 private Attribute linked;//linked attribute

7 public int mod;//any additional dicepool modifiers

8 private int pool;//the total dicepool

9}

10public Skill(int rating,int modifier,Attribute att){

11 rat=rating;

12 mod=modifier;

13 linked=att;

14 pool=rat+att.getAugRat()+mod;

15}

now netbeans is telling me that a class interface or enum is expected for lines 10,12,13,14, but not 11. I have no idea why this might be. Attribute is an object i created in the default package, but as you can see rat mod and pool are just integers. it also had this problem with a string before i removed it. i also noticed that attribute is not highlighted in blue as int is (to indicate that it is a recognized object). can anyone tell me what might be the cause of this?
