arraylist - Java sharing same values in a class

Question

I have a class called Hand and another class to test it. Hand uses global variables and change their values with some methods if in class test I create two variables of the Hand class changes in one of the variables will affect the other. How can I make them separate ?

Class Hand:

private static List<Card> hand = new ArrayList<Card>();

Class Test:

        Hand hand1 = new Hand();
        Hand hand2 = new Hand();

If I add values to hand1 arraylist it changes also the values of hand2 arraylist. Can I separate them?

Answer 1

Turn the private static List<Card> into a private List<Card>.
