Compare an Object to an Enum list

[Declan Dee]

Greetings All,

My name is Declan and I am new to both Java programming, programming in general and of course this site.

I hope to get to know you all in the coming years (!)

My first question is this. I have the following two Enums:

public enum CardSuit { SPADES, CLUBS, DIAMONDS, HEARTS } and

public enum CardRank { DEUCE, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT, NINE, TEN, JACK, QUEEN, KING, ACE }

I create an object (card1) with the following constructor:

public card (String suit, String rank) {
this.name = name;
this.rank = rank;
}

My question is, how do I compare the card1 object to these Enums?

For example if my object is Card1 (Spades, Six) and I create a second object (Hearts, Two), I want to have it that because SPADES is first (higher) in the Enum list that object1 (Card1) is automatically higher that object2 (Card2).

I have to write a program that compares the values of cards.

I have been working with CompareTo() with little success

Any help is greatly appreciated

Thanks in advance

Declan

You could do Something like that

    class Card { //always use upcase letters for classes
	
	private String suit;
	private String rank;

	public Card(String suit, String rank){
		this.suit = suit;
		this.rank = rank;
	}
	
	public boolean isSame(CardSuit suit, CardRank rank){
		if(this.suit.equalsIgnoreCase(suit.toString()) && this.rank.equalsIgnoreCase(rank.toString())){
			return true;
		} else {
			return false;
		}
	}
}

enum CardSuit { SPADES, CLUBS, DIAMONDS, HEARTS }  

enum CardRank { DEUCE, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT, NINE, TEN, JACK, QUEEN, KING, ACE } 

But I think it is better to change the attributes of the class card to match the enums, ex:

 
class Card {
	
	private CardSuit suit;
	private CardRank rank;

	public Card(CardSuit suit, CardRank rank){
		this.suit = suit;
		this.rank = rank;
	}
	
	public boolean isSame(CardSuit suit, CardRank rank){
		if(this.suit == suit && this.rank == rank){
			return true;
		} else {
			return false;
		}
	}
}

Using the Comparable interface...

   
public class Card implements Comparable<Card>{ 
	
	private CardSuit suit;
	private CardRank rank;

	public Card(CardSuit suit, CardRank rank){
		this.suit = suit;
		this.rank = rank;
	}

	public int compareTo(Card other) {
		return this.rank.compareTo(other.rank);
	}
}
