this code isn't working so what's wrong with it?

1.       for(int i < ffighters.size()-1; i<10; i++) {
         fFighter ff = (fFighter)ffighters.get(i);
        
         if(ff.moving){

         }
         else{
           ff.moving = true;
         }
         break;
       }
         }

i'm not very good on arrays but what i've worked out is that in the first line the 'ffighters.size()-1 is the object that was created most recently; if you put -2 on the end of it it's the second most recent object. how do i get every object in the FOR line?
