Loop for players

[Dheesan Dabycharun]

Hi guys,

Currently programming a game in java in which i want to have the below:-
1. user can play with computer.
2. user can choose to select from 2 to 4 players.

So far i can only make 2 players work using the following method.

public void changePlayer () {

// loop for currentPlayer

if (currentPlayer == player1) {
currentPlayer = player2;
} else if (currentPlayer == player2) {
currentPlayer = player1;
}

1. How can make the computer be the player?
2. How can i add up to 4 players in this loop?
(tried to make more than 2 player in the above but the token is not moving.
3. Thought of using a loop like but bit confused how to make it.
for (int i = 0; i<4; i++)

Thanks in advance.

1) Make it a Player instance, or the instance of a special subclass that does not need user interaction.
2+3) Use an array (or even better, a List) with an index that specifies the current index. In pseudo code:

private List<Player> players;
private int index;

public Game()
{
    players = new ArrayList<Player>();
}

public void addPlayer(Player player)
{
    players.add(player);
}

public void start()
{
    int index = 0;
    while (true)
    {
        Player current = players.get(index);
        current.makeMove();
        index = (index + 1) % players.size(); // increases but makes 0 again if the last player just made his move
    }
}
