Question

Anyone???? Hi, in my black jack game i implemented splits by first asking the player to double down and if he rejects then i allow him to split:

while(true){
    for(int j=0;j<2;j++){
        if(players[i].splits[j].getStatus() != true){ // splits is an array of two players hand 1 and hand 2
            System.out.print("Choose your next move, " + players[i].name + ", Hand "+ players[i].splits[j].number + ": \n" + "Points: " + players[i].splits[j].points + "\n" + "Hint: ");
            getHints(players[i].splits[j]);
            System.out.print( "\n1)Hit\n2)Stand\n");
            System.out.println();

            x2 = IO.readInt();
            if (x2==2){
                players[i].splits[j].standed = true; // if player stand...
                break;
            }else if(x2 == 1){//else deal a card
                Card c = dealCard(deck);
                updatePoints(players[i].splits[j], c);
                addCard(players[i].splits[j], c);
                System.out.println(players[i].name + ", Hand "+ players[i].splits[j].number + " was dealt:  " + c.showCardValue() + " of " + c.showCardSuit() );
                boolean isBusted = testPoints(players[i].splits, j); // test for busted
                if (isBusted == true){
                    System.out.println("BUSTED!!!!!!!!!");
                    players[i].splits[j].busted = true;
                    break;
                }
            }
        }
        System.out.println(players[i].name + ", Hand " + players[i].splits[j].number + " Points: "+ players[i].splits[j].points);
//                                          printStats(players[i].splits[j]);

    }
//check to end loop if split is busted to stands...
}

when i print the players stats i get the memory location instead of the text, can any one please help. Thank you, if you need more information please say so so i can update it.

splitPlayer class:

public class splitPlayer {

    public int points = 0;
    boolean busted = false;
    boolean standed = false;
    int number = 0;
    int ace = 0;
    String name = "";
    Card[] cardsDealt = new Card[12];


    public splitPlayer(int number, int points){
        this.number = number;
        this.name = "Hand "+ number;
        this.points = points;
    }
    public boolean getStatus(){
        if(busted == true || standed == true ){
            return true;
        }else{
            return false;
        }
    }
    public void setPoints(int points){
        this.points += points;
    }
}

updatePoints:

public static void updatePoints(splitPlayer player,  Card c){

        int point = c.getValue();

        if (point == 1){


            player.ace += 1;
            player.setPoints(11);


        }else{
            player.setPoints(point);
        }

        if (player.points > 21 && player.ace > 0) {
            player.points -= 10;
            player.ace --;
        }





        return;
    }

Answer 1

The culprit appears to be this line of code:

System.out.println(players[i].name + ", Hand " + players[i].splits[j].number + " Points: "+ players[i].splits[j].points);

To figure out what is wrong, you need to know what the type of players[i].splits[j].points is. According to the output, it appears to be an instance of the splitPlayer class. You might be able to solve the problem by overloading the toString() method of this class. I can’t know for sure without confirmation that the above line of code is really causing the problem. I also need to see more of your code, in particular the declaration of the points data member which is used here.

Addendum:

The reason that you see splitPlayer@1a758cb in the output is because you are concatenating an object with a String. Java will automatically call the toString() method of the object. If the object’s class does not provide a toString() method, the one in Object will be called which gives the output you see.
