I've got a bit of code that takes compares entries in an array, but it's a hell of a mess and I'm sure there's a smarter way of doing it, I was wondering if anyone could point me in the right direction.

I've got an array of tab separated information in the format:

1.  "name '\t' var1 '\t' var2 '\t' var3 '\t' var4 '\t' var5 '\t' var6 '\t' var7"

where each of the vars is a number between 1 and 7. What I want to do is compare each of the array entries, but only in the 'column' in which it's in, and where there's a match, work out the percentage correlation between the entries.

My current code relies on a set of nested for loops:

1. public void crunchData() {
2.         for( int i = 0; i < allData.length; i++){
3.        
4.         String[] current = split(allData[i], '\t');
5.            
6.             for( int j = 0 ; j < allData.length; j++){
7.                 int counter = 0;
8.                 String[] compare = split(allData[j], '\t');
9.            
10.                 if ( current[0].equals(compare[0]) == false){
11.                    
12.                
13.                     for( int k=0; k < current.length ; k ++){
14.                         if(compare[k].equals(current[k]) == false) {
15.                             counter++;
16.                         }
17.                     }
18.                 }
19.                 if (counter>0){
20.                     float percentage = (counter/(current.length-1)) * 100;      
    
21.                 }
22.             }
23.         }
24.     }

As you can see this is a pretty ugly way of doing business. I was wondering if anyone had any suggestions for how to structure this snippet a bit more conveniently/economically/whatever?

Thanks!
