A Card class has been defined with the following data fields. Notice that the rank of a Card only includes the values from Ace - 10 (face cards have been removed):
class Card {
private int rank; // values Ace (1) to 10
private int suit; // club - 0, diamond - 1, heart - 2, spade - 3
public Card(int rank, int suit) {
this.rank = rank;
this.suit = suit;
}
