arraylist - Java 2d game finding correct enemy for fighting -

i making simple 2d game in java , trying fighting work. going pokemon-style fighting, doing when press spacebar, checks if colliding enemy, finds enemy in arraylist, , executes fight method using enemy. works of time, can't seem find enemy in arraylist. code checking is:

if (space) {         (rectangle collideable : enemy.ens) {             if (intersects(playerr, collideable)) {                 system.out.println("colliding enemy!");                 x = locx;                 y = locy;                 playerr.setlocation(x, y);                  (int = 0; < game.enemies.size(); i++) {                      if (enemy.ens.get(i).equals(collideable)) {                         system.out.println("can't find enemy fight");                         system.out.println(game.enemies.get(i).getname());                         fightquestion(game.enemies.get(i), i);                         break;                      }                 }                  break;             }         }     } 

enemy.ens created when render each enemy. game.enemies created when read in of enemy stats, , add each enemy arraylist. every enemy try fight, getting point prints out colliding, not fight part. ideas why happening fantastic!

edit code when game.enemies filled:

public static void loadenemies() {     im = getimagemanager();     scanner qwe;     try {          qwe = new scanner(new file("enemystats.txt"));         while (qwe.hasnextline()) {             string name = qwe.nextline();             string origin = qwe.nextline();             string weapon = qwe.nextline();             string gear = qwe.nextline();             string spec = qwe.nextline();             int hp = qwe.nextint();             int att = qwe.nextint();             int def = qwe.nextint();             int randx = (int) (math.random()*(18*scale*tilesize));  //give random x coordinate             int randy = (int) (math.random()*(18*scale*tilesize));  //give random y coordinate             if(qwe.hasnextline()){                 qwe.nextline();             }             enemies.add(new enemy(randx,randy,im,name,origin,weapon,gear,spec,hp,att,def));     //adds enemy arraylist              int randi = (int) (math.random()*enemies.size());              for(int = 0; < 4;i++){      //adds enemy arraylist rendered                 enemiestorend.add(enemies.get(randi) );             }            }       }       catch (filenotfoundexception e) {         e.printstacktrace();     } } 

why execute statement:

system.out.println("can't find enemy fight"); 

for each iteration in second loop, regardless of checking condition first? , why second loop check:

i < game.enemies.size(); 

instead of:

i < enemy.ens.size();
