Question

I’m trying to Display individual elements of an Object I have created.

It is a simple Java program that allows users to add and keep track of Player Details.

I’m just stumped when it comes to displaying the details after they have been added already. here is what my code looks like

I can create the object and input it into the arraylist no problem using the case 2, but when I try to print it out I want to do something like

System.out.println("Player Name" + myPlayersArrayList.PlayerName + "Player Position" + myPlayerArrayList.PlayerPosition + "Player Age" + "Player Age");

I know that is not correct, but I dont really know what to do, if anyone can be of any help it would be greatly appreciated. Thanks

System.out.println("Welcome to the Football Player database");
 System.out.print(System.getProperty("line.separator"));


     UserInput myFirstUserInput = new UserInput();
    int selection;
            ArrayList<Player> myPlayersArrayList = new ArrayList<Player>();

            while (true) {

                System.out.println("1. View The Players");
                System.out.println("2. Add A Player");
                System.out.println("3. Edit A Player");
                System.out.println("4. Delete A Player");
                System.out.println("5. Exit ") ;
                System.out.print(System.getProperty("line.separator"));

                selection = myFirstUserInput.getInt("Please select an option");
                System.out.print(System.getProperty("line.separator"));
                switch(selection){


        case 1: 

                        if (myPlayersArrayList.isEmpty())
                                    {
                        System.out.println("No Players Have Been Entered Yet");
                        System.out.print(System.getProperty("line.separator"));
                        break;}

                        else 
                        {for(int i = 0; i < myPlayersArrayList.size(); i++){
                            System.out.println(myPlayersArrayList);

        }
                    break;

                    case 2:  {

                        String playerName,playerPos;
                        int playerAge;

                                playerName = (myFirstUserInput.getString("Enter Player name"));
                                playerPos = (myFirstUserInput.getString("Enter Player Position"));
                                playerAge = (myFirstUserInput.getInt("Enter Player Age"));   

                                myPlayersArrayList.add(new Player(playerName, playerPos, playerAge));   ;
                                                        break;
                    }

You need to use index to access individual element: –

for(int i = 0; i < myPlayersArrayList.size(); i++){
    System.out.println(myPlayersArrayList.get(i));
}

Then you can override toString() method in your Player class

public String toString() {
    return playerName + " : " + playerAge + " : " + playerPosition;
}
