Creating unspecified ammount of objects

[plm-pusik]

Hey, I am making a DOS game where you can be multiple players. Therefor I have a class called "Player" that I create objects from.

In the beginning of the game I want the player to choose how many players that shall participate and then I want to create that many "Player" objects, how would I do this? I know how to ask the player how many players that shall participate but I don't know how to create unspecified ammount of objects!

Example 1:
Player says: "I want there to be 3 players in this game"
*Program creates 3 Player objects called player1, player2, player3* <- The part I need help with!

Example 2:
Player says: "I want there to be 5 players in this game"
*Program creates 5 Player objects called player1, player2, player3, player4, player5* <- The part I need help with!



I hope I made myself clear and thank you for the help.

You have to understand that in your example, the # of elements is specified. Ask the client how many player would like to play and store that answer in a variable. There you go. You now know how many players are going to play. Example:

Scanner cin = new Scanner(System.in);
System.out.print("How many players would like to play this game? ");
int numbOfPlayers = cin.nextInt();
System.out.println(numbOfPlayers + " number of players will be playing.");

You can now make an array of Players with numbOfPlayers elements. Finally, iterate through that array and initialize a Player for every element.

creates 5 Player objects called player1, player2, player3, player4, player5

Is your problem with the creating of these 5 named variable at execution time?
It can't be done. All variables are given names at compile time.
You can use a Map object to give an object a name:
HashMap hp = new HashMap();
hp.put("player1", new Player(1)); // use key for name of object

I was a bit unsure about how to describe what I wanted, so good thing you corrected it. Thanks for your answer, I'll probably use arrays like you said.

Yeh I'm guessing my problem is with creating the 5 variables at execution time. My first idea was that maybe you could do something similar to how you build strings but I guess that ain't possible then. I'll just use arrays for now, but I'll be checking out HashMaps for sure.
