Question

The goal for me is that I need to identify the objects needed for the UNO card game and the actions that those objects perform, rather than how the objects are suppose to actually be represented. I need to write a document that includes an ADT (abstract data type) for each object needed in my program. This is a partial ADT for the UnoCard class.

//get the color of the card

+getColor(): String

//set the color of the card

+setColor(color : String):void

//get the value of the card

+getValue(): int

//set the value of the card

+getValue(val : int): void

//return true if card has same value or

//same color as the card

//return false otherwise

+isMatch(card: UnoCard): boolean

The standard UNO card must be able to report both its color and value, and, when given another card, tell whether or not it is a "match." Sounds not to simple for me since I never played the real card game. I am using java/NetBeans. Thank You.

//Java program

class UnoCard{
   private String color;
   private int value;
  
   public UnoCard(String color , int val) {
       this.color = color;
       value = val;
   }
   public String getColor() {
       return color;
   }

   //set the color of the card

   public void setColor(String color ) {
       this.color = color;
   }

   //get the value of the card

   public int getValue() {
       return value;
   }

   //set the value of the card

   public void setValue(int val) {
       value = val;
   }

   //return true if card has same value or

   //same color as the card

   //return false otherwise

   public boolean isMatch(UnoCard card) {
       return (this.value==card.value)||(this.color==card.color);
   }
}

public class Card {
   public static void main(String args[]) {
       UnoCard card1 = new UnoCard("Red",10);
       UnoCard card2 = new UnoCard("Green",10);
       UnoCard card3 = new UnoCard("Blue",15);
      
       if(card1.isMatch(card2))System.out.println("Match");
       else System.out.println("No Match");
      
       if(card2.isMatch(card3))System.out.println("Match");
       else System.out.println("No Match");
   }
}
