swing - Java : Memory Game -

i working on memory game project, click on 2 cards check if pictures same or not. problem facing if both cards don't have same picture, second picture not appear , first 1 closes well.

here code think has sort of error in.

 public void actionperformed(actionevent e)              {                                             clicks +=1;                  card clicked = (card)e.getsource();                  clicked.changecolor();                  for(int i=0;i<16;i++)                      if(clicked == cards.get(i))                          opencardindices.add(i);                     if(clicks==2 && opencardindices.get(opencardindices.size()-1)!=opencardindices.get(opencardindices.size()-2))                   {                     if(cards.get(opencardindices.get(opencardindices.size()-1)).equals(cards.get(opencardindices.get(opencardindices.size()-2))))                     {                         (cards.get(opencardindices.get(opencardindices.size()-1))).removeactionlistener(this);                         (cards.get(opencardindices.get(opencardindices.size()-2))).removeactionlistener(this);                     }                     else                     {                          opencardindices.remove(opencardindices.size()-1);                         opencardindices.remove(opencardindices.size()-1);                         //lockcards();                         unlockcards();                     }                     clicks = 0;                  }    

your code tells that.

you want else clause like:

• delay 2 seconds before hiding cards unlock.

or maybe

• leave cards alone until click on 1 of them again. require counter going 1 2 , 3, turn them over.

not gonna write code clue.
