paintComponent is executing twice

Question

This is bothering me, my code works and runs but when I went to run it, it seems to be looping my for loops twice, can anyone help me with my logic? Thanks...

Answer 1

       for(int i = 0; i < radius.length; i++)
       {
           for (int j = 0; j < radius.length; j++)
           {

Most loops where you wish to compare every pairing of two elements together is instead written like this:

       for(int i = 0; i < radius.length; i++)
       {
           for (int j = i; j < radius.length; j++)
           {

(Note the j = i in the second loop.)

This also lets you remove the i != j test. :)

EDIT: Oops; j = i means you still need to i != j test -- if you used j = i+1 then you can remove the i != j test. Sigh. :)
