Question

Hi I am new to the java programming. I have a instance variable in a class which I should call to another class.It should not be static as per the requirements.The code given below## `

public class Card {

    private String no;
    private String text;
    public Vector totalCards = new Vector();

    public String getNo() {
        totalCards.addElement(no);
        return no;
    }

    public void setNo(String no) {
        this.no = no;
    }

    public String getText() {
        totalCards.addElement(text);
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }
}

I need to pass this “totalCards” vector in another class without making it as a static.How can I pass this value.Can anybody help me. Any suggestions appreciated.

It’s a bit unclear exactly what your issue is, but you first need to have an instance of Card. The totalCards Vector will then live in that Card object.

Card myCards = new Card();

Now the object that has access to myCards can access the Vector with:

myCards.totalCards

However, it’s considered a better practice by many to make totalCards private and make a getter for it:

myCards.getTotalCards();
