java - Adding my items to an ArrayList -


i have created 52 cards added arraylist problem when try first item in list can outofboundserror because don't think has been added arraylist.

private arraylist<card> deck;  public deck() {     deck = new arraylist<card>();     for(int = 1; < 14; i++) {         if(i == 1){             card c = new card("ace", "hearts");         }         else if(i < 11 && > 1) {             card c = new card("" + i, "hearts");         }         else if(i == 11) {             card c = new card("jack", "hearts");         }         else if(i == 11) {             card c = new card("queen", "hearts");         }         else if(i == 11) {             card c = new card("king", "hearts");         }     }      for(int = 1; < 14; i++) {         if(i == 1) {             card c = new card("ace", "clubs");         }         else if(i < 11 && > 1) {             card c = new card("" + i, "hearts");         }         else if(i == 11) {             card c = new card("jack", "clubs");         }         else if(i == 11) {             card c = new card("queen", "clubs");         }         else if(i == 11) {             card c = new card("king", "clubs");         }     }      for(int = 14; < 1; i--) {         if(i == 11) {             card c = new card("king", "diamonds");         }         else if(i == 11) {             card c = new card("queen", "diamonds");         }         else if(i == 11) {             card c = new card("jack", "diamonds");         }         else if(i < 11 && > 1) {             card c = new card("" + i, "diamonds");         }         else if(i == 1) {             card c = new card("ace", "diamonds");         }     }      for(int = 14; < 1; i--) {         if(i == 11) {             card c = new card("king", "spades");         }         else if(i == 11) {             card c = new card("queen", "spades");         }         else if(i == 11) {             card c = new card("jack", "spades");         }         else if(i < 11 && > 1) {             card c = new card("" + i, "spades");         }         else if(i == 1) {             card c = new card("ace", "spades");         }     } }

how go adding arraylist?

to add cards deck need call 

deck.add(c);

btw pointless using loop , checking 1 value in loop. can call line of code once.

list<card> deck = new arraylist<>(); (string suit : "hearts,clubs,diamonds,spades".split(",")) {    deck.add(new card("ace", suit));    (int = 2; <= 10; i++)        deck.add(new card("" + i, suit));    deck.add(new card("jack", suit));    deck.add(new card("queen", suit));    deck.add(new card("king", suit)); }
