Hey,

to access the values of a two-dimensional array you would have to use two pairs of brackets. To use the string in calculation, you have to convert them to a number, and then convert them back into a string to store them again.
Could you explain, why you have to use a String-array? Wouldn't it be easier to parse the strings once and store them in an int-array, for further calculations?
For a string-array, it could work like this:

1. String[][] meh = new String[5][8];
   
   for (int i=0; i<meh.length; i++) {
     for (int j=0; j<meh[0].length; j++) {
       meh[i][j]="1";
     }
   }
   
   for (int i=0; i<meh.length; i++) {
     int value = int(meh[i][1]);
     meh[i][1] = Integer.toString(++value);
   }
   

Would be better to store strings an ints in different arrays.
Or create a Club-class, that stores names and scores (and all the other properties, that might belong to each club), that would be the most elegant way in opinion.

like this...?

for images: you'll find an ok set here:

1. // spades (♠), hearts (♥), diamonds (♦) and clubs (♣).
2. final int spades= 0;
3. final int hearts = 1;
4. final int diamonds = 2;
5. final int clubs = 3;
6. 
   
7. // additional (redundant) color
   
8. final int clubColorBlack = 0;
9. final int clubColorRed   = 1;
10. 
    
11. class Club {
12. String clubName ;
13. int clubSuit; // The four French playing card suits used primarily in the English speaking world:
    
14.                   // spades (♠), hearts (♥), diamonds (♦) and clubs (♣).
15.                   // use const above
    
16. int clubScore ;
17. int clubColor ;          // black or red / use const above
18. PImage clubeImage ;
    
19. boolean clubJoker;
    
20. }

That is some thing I'm aways in doubt about... Is aways, or at least usually, better to make a class to hold variables together? Isn't this taking more memory and slowing things?  Fore sure makes thing easier to control...
