Accessing objects of other classes

Question

I've recently picked up Java and have run into a problem. I have several files with different classes, but I can't figure out how I can access objects of the other classes in files other than the one they were declared in. For example:

player.java:
public class Player 
{
    public static void main(String[] args) {
        Player player = new Player();
    }
    public int getLocation()
    {
         return 2;
    }
}

monster.java:
public class Monster
{
    public void attackPlayer()
    {
        player.getLocation();
    }
}

I'm not sure how I can access these objects of other classes effectively from other files and classes themselves? I know I could make the objects static and then access them as variables through the class they were made in, but that seems rather counter-intuitive? I come from a less object-oriented programming background so I'm still trying to understand java's style of programming.

Answer 1

A good place to start would be to pass in the player you want to attack "when" the monster attacks.

battle.java

public class Battle {

  public static void main(String[] args) {
    Player player = new Player();
    Monster monster = new Monster();
    monster.attackPlayer(player);
  }
}

player.java:

public class Player 
{
    public int getLocation()
    {
         return 2;
    }
}

monster.java:

public class Monster
{
    public void attackPlayer(Player player)
    {
        player.getLocation();
    }
}
