I need some help with composition, i think

[Nerijus]

Hi I am new in this forum so sorry if it isn't proper place to ask this question. So the question:
I have two classes:
public class card {

public void increase(Bankomatas b,int money){
themoney=b.papildymas(100, this);
System.out.println("It's OK");

}
}

public class Bankomatas {

public int money;
private int diabetas=2000;

public Bankomatas(int money){
this.money=money;
}

public themoney papildymas(int sask, card kor){
saskaita+=sask;

return null;

}
}

Error is in red. How I should it improve? :)

You are using 'themoney' as a variable at one place and as a return type at another place; that doesn't make sense.

kind regards,
