Question

I made two classes. The first one is the Player class and the second the Bag. What I want is to print the score of the player in main(). In Bag, I count the score and I want to set it in Player. This is a part of the Bag class

 public void count( int number)
 { ............. 
   scr=k*2;//gives an int
   setScore(scr);//set the score in Player class
 }

Player:

public class Player {

public Player() {
}

private String name;
private int score;

public Player(String name, int score) {
    this.name = name;
    this.score = score;
}
 public String getName() { 
     return name;
 }

public void setScore(int score) {
    this.score = score;
}

public int getScore() {
    return score;
}

In main() I try to print the score with this code but I can’t:

Player p=new Player();
System.out.println( p.getScore());

It returns me score=0 (which I set it at the begging of main)
I hope that you understand what I want to say.

For this to work, the Bag class should have a reference to the Player class. So essentially you should change your code to follow the below pattern

class Bag
{
  private Player p;

  public void setPlayer(Player pp)
  {
    p=pp;
  }

  public Player getPlayer()
  {
    return p;
  }

 public void count( int number)
 { 
   scr=k*2;//gives an int
   p.setScore(scr);//set the score in Player class
 }
}

And your main method

Player p=new Player();
Bag b=new Bag();
b.setPlayer(p);
b.count(5);
System.out.println( p.getScore());
