Java: determining the name of an object?

I am working on a small tiny game where there is an attacker and defender.

        Player Attacker = new Player();
        Player Deffender = new Player();

    }
}
class Player{
    int armees = 0;
    int tarningar = 0;
    Dice Dices[];
    Player(){
        armees = 10;
        // if object name is Attacker, tarninger = 3, if defender = 2
        Dices= new Dice[tarningar];
        for(int i=0;i<Dices.length;i++){
            Dices[i]=new Dice();
        }
    }
}

I commented inside the above code where I want to have an if statement to determine how many cubes it should have.

If this is impossible to do, maybe another way to do it?

I also tried

Attacker.tarningar = 3;
Deffender.tarningar = 2;

right in the place where the object is mainly defined, but it does not work, because it already executed Player () inside the class.

(im still new for java) thanks

Perhaps you could do:

Player(boolean isAttacker){
    armees = 10;
    // if object name is Attacker, tarninger = 3, if defender = 2
    int diceNum;
    if (isAttacker) diceNum = 2;
    else diceNum = 3;
    Dices= new Dice[diceNum];
    for(int i=0;i<Dices.length;i++){
        Dices[i]=new Dice();
    }
}

Then you will need to inform the player that he is attacking or defending when he is created.

Player p = new Player(true); // creates an attacker

change your code to this:

  Player Attacker = new Player(true);
        Player Deffender = new Player(false);

    }
}
class Player{
    boolean attacker;
    int armees = 0;
    int tarningar = 0;
    Dice Dices[];
    Player(boolean attacker){
        this.attacker = attacker;
        armees = 10;
        tarninger = attacker ? 3 : 2;
        Dices= new Dice[tarningar];
        for(int i=0;i<Dices.length;i++){
            Dices[i]=new Dice();
        }
    }
}

If you are trying to differentiate based on variable names, this is not possible because this information is deleted during compiler optimization. If instances are available, you can do

if (this == attacker)
{
    ...
}

or you can enter a new field to store the name

Player attacker = new Player("Attacker");

or perhaps an enumeration.

Player attacker = new Player(PlayerType.Attacker);
