Question

In java

How to get started;

Create a class called Card. The card has three fields; a value , a suit and a face.

The card class has a constructor that takes three values for the three fields.

Create a no-args constructor.
The Card class has three get methods to return the values of each of the fields.

The Card class has a toString( ) method.

The Card class has a compareTo( ) method that uses the value of the card to determine the ordering.

Create an equals( ) method that returns true if the parameter Card has the same suit and the same face as the invoking Card.

Create a class called Deck. A deck has two fields- an array of Cards and an int which holds the subscript of the Card at the top of the deck.
The Deck class will have only one constructor, which will create the array. Try to think of a way to code this without writing 52 statements. (not required)

The Deck class also has a method getTopCard( ) which returns a copy of the Card that is at the top of the array. Notice this means the Card class needs a copy constructor.

The Deck class has a method called shuffle( ) which shuffles the array of Cards. To shuffle, generate random numbers and use these to exchange array elements. Exchange 1000 times in this method.

Display a test of your Card class and Deck class in a main( ) that

Prints the entire Deck before shuffling, prints the Deck after a shuffle and

Draws and prints the top two Cards.

Programming Language:java

File Name:Deck.java

As u mentioned The Deck class will have only one constructor, which will create the array. Try to think of a way to code this without writing 52 statements. (not required) in Question I didn't code for this section.

Sourcecode:

import java.util.*

public class Card{
int value=new int();
String suit=new String();
int face= new String();
public Card(int v,String s,String f)
{
this.value=v;
this.face=f;
this.suit=s;
}
public Card(){
this.value=0;
this.face="";
this.suit="";
}
public int getvalue(){
return value;
}
public int getsuit(){
return suit;
}
public int getface(){
return face;
}
public String toString(int value,String suit){
if (suit == JOKER) {
if (value == 1)
return "Joker";
else
return "Joker #" + value;
}
else{
String s;
String va;
switch ( suit ) {
case SPADES: s="Spades";
case HEARTS: s="Hearts";
case DIAMONDS: s="Diamonds";
case CLUBS: s= "Clubs";
default: s= "Joker";
}
switch (value) {
if ( suit== "JOKER")
return "" + value;
else {
switch ( value ) {
case 1: va="Ace";
case 2: va= "2";
case 3: va= "3";
case 4: va= "4";
case 5: va= "5";
case 6: va= "6";
case 7: va= "7";
case 8: va= "8";
case 9: va= "9";
case 10: va= "10";
case 11: va= "Jack";
case 12: va= "Queen";
default: va= "King";
}
}
retrun s +" of "+va;

}
public String compareTo(Card va){
//determines the order of the cards with the help of card value

}
public boolean equals(Card c){
if(this.suit==c.suit && this.face==c.face)
return true;
else
return false;

}
}
public class Deck{
Card arr[]=new Card();
int subscript=new int();
public Card Deck(){
//in question said that this method is not required
}
public Card getTopCard(){
return Card.arr[arr.length-1];//returns the top card of the array card
}
public void shuffle()
{
for ( int i = arr.length-1; i > 0; i-- ) {
int ran = (int)(Math.random()*(i+1));
Card tem = arr[i];
arr[i] = arr[ran];
arr[rand] = tem;
}
}
public static void main(String[] args) {
for(int i=0;i<arr.length;i++){
System.out.println(Deck.arr[i]);
}
Deck d=new Deck();
d.shuffle();
for(int i=0;i<arr.length;i++){
System.out.println(d.arr[i]);
}
System.out.println("First Top Card "+d.arr[arr.length-1]);
System.out.println("Second Top Card"+d.arr[arr.length-2]);
};

}

In Addition You have to add Card data to do further computation.
