Question

1. Create a new class called Card that contains the following attributes: [3 K]

• Suit (Clubs, Diamonds, Spades, Hearts)

• Value (do not use Jack, Queen, King, Ace, instead, the value of your cards should be 1-13 where 11 = jack, 12 = Queen, 13 = King, and 1 = Ace)

• Colour (Red or Black)

2. Make two constructions for your card: [2 A]

• A default constructor for when you create an object without any arguments

• A constructor that has 3 parameters, one for each attribute

• Card should overwrite the corresponding print method to print the card nicely to the user with the following layout (colour does not need to be outputted): [1 K]

Value of Suit

ex. "5 of Hearts"

3. Card should also contain the following methods/functions:

• isRed() – returns true or false if the card is Red [1 I]

• isLarger(card)– takes in a card and returns the larger card according to the values. Note Ace (1) is smallest card and King (13) is largest. If the cards are the same, return the card the method is called on. [2 I]

• copyCard() – creates and returns a new card object with all the same attributes [2 I]

In the main, feel free to test your methods in any way. The test cases will not be affected by any print statements. You must submit before lunch even if all the tests do not pass. Note that commenting is necessary and will count for 2 marks. [2 C]

[4 K, 5I, 2C, 2A]

Main.java

class Main {
public static void main(String[] args) {

class Card {
  
  
}

Code Explanation:

Define the class Card.

1. Enum for Colour To Possible Values RED, BLACK
2. Enum For Suit With Possible Values Clubs, Diamonds, Spades, Hearts
3. Define the instance variables for the Colour, Suit and Value
4. Constructor overloading implemented in the form of Default Constructor and parameterized constructor with values as Colour,Suit And Value
5. isRed() method implemented , it checks if Suit is Hearts or Diamonds if so returns True else False
6. isLarger() method implemented, it checks if current card value>=passed card value, if so returns current card else the passed card.
7. copyCard() method implemented, this will create a new card object with values of current Card Object
8. toString() method implemented, this basically is used to print the Card in a nice format i.e {Value} Of {Suit}

2. The Main class, it is the driver program.

Here, the object of Class Card is created and respective methods created above are called to try out the functionalities developed.
