我可以使用构造函数修改私有静态数组吗？

Question

我有一个叫做cardNames的类。在每个新游戏中，我都会创建一个新的cardNames实例，该实例对应于当前使用的卡牌。我希望将它们设置为静态，这样就不必发送cardNames对象的副本。

这合法吗？

public class cardNames 
{
    private static String[] characters;
    private static String[] weapons;
    private static String[] rooms;
    private int totalCards;

    public cardNames(String[] theCharacters, String[] theWeapons, String[] theRooms)
    {
        characters = Arrays.copyOf(theCharacters, theCharacters.length);
        weapons = Arrays.copyOf(theWeapons, theWeapons.length);
        rooms = Arrays.copyOf(theRooms,  theRooms.length);
        totalCards = characters.length + weapons.length + rooms.length;
    }

    public static String[] getCharacters()
    {
        return Arrays.copyOf(characters, characters.length);
    }

创建新的cardName对象后，我会有一套新的角色，武器和房间吗？
