Deck of Cards issue -Java -

i having problems getting deckofcards class compile. keeps telling me cannot find symbol when pointing deck2.shuffle() , deck2.deal(). ideas why?

import java.lang.math; import java.util.random;  public class deckofcards {     private cards[] deck;     private int cardhold;      public deckofcards() {         deck = new cards[52];         int n = 0;         (int = 1; <= 13; i++) {             (int j = 1; j <= 4; j++) {                 deck[n] = new cards(i, j);                 n = n + 1;             }         }         cardhold = -1;     }      public void shuffle() {         // shuffles ands resets deck         int = 0;         while (i < 52) {             int rando = (int) (5.0 * (math.random()));             cards temp = deck[rando];             deck[rando] = deck[i];             deck[i] = temp;             i++;         }     }      public cards deal() {         // if there more cards left in deck, return next 1 ,         // increment         // index; return null if cards have been dealt         // ***question, increment before or         // after??***----------------------------------------         if (!hasmorecards()) {             return null;         } else {             cards temp = null;             temp = deck[cardhold];             cardhold = cardhold + 1;             return temp;         }     }      public boolean hasmorecards() {         // returns true if there more cards left, else return false         if (cardhold == 0)             return false;         else             return true;     }      public static void main(string[] args) {         deckofcards deck2 = new deckofcards();         deck2.shuffle();         (int = 0; < 52; i++)             system.out.println(deck2.deal());     } } 

below class card class, maybe causing issue?

public class cards {     protected int rank;     protected int suit;     protected string[] snames = { "hearts", "clubs", "spades", "diamonds" };     protected string[] rnames = { "ace", "2", "3", "4", "5", "6", "7", "8",             "9", "10", "jack", "queen", "king" };      public cards(int rank, int suit) {         suit = suit;         rank = rank;     }      public string tostring() {         return ("your card is: " + rnames[rank - 1] + " of " + snames[suit - 1]);     }      public int getrank() {         return rank;     }      public int getsuit() {         return suit;     }  } 

your compiler issues behind you, there lots of issues code.

public class deckofcards {     private cards[] deck;     private int cardhold;      public deckofcards() {         deck = new cards[52];         int n = 0;         (int = 1; <= 13; i++) {             (int j = 1; j <= 4; j++) {                 deck[n] = new cards(i, j);                 n = n+1;             }         }         cardhold = -1;     }      public void shuffle() {         int = 0;         while (i < 52) {             int rando = (int) (5.0*(math.random()));             cards temp = deck[rando];             deck[rando] = deck[i];             deck[i] = temp;             i++;         }     }      public cards deal() {         return (hasmorecards() ? deck[++cardhold] : null);     }      public boolean hasmorecards() {         return (cardhold != 0);     }      public static void main(string[] args) {         deckofcards deck2 = new deckofcards();         deck2.shuffle();         (int = 0; < 52; i++)             system.out.println(deck2.deal());     } } 

and:

public class cards {     protected int rank;     protected int suit;     protected string[] snames = {"hearts", "clubs", "spades", "diamonds"};     protected string[] rnames = {"ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "jack", "queen", "king"};      public cards(int rank, int suit) {         this.suit = suit;         this.rank = rank;     }      public string tostring() {         return ("your card is: "+rnames[rank-1]+" of "+snames[suit-1]);     }      public int getrank() {         return rank;     }      public int getsuit() {         return suit;     } }
