In the most common use of the term, a class can be seen as a blueprint used to create objects. In other words, object(s) are created from a class in Java.
<h3>Creating a Class</h3><h3>Code:</h3>
import java.util.*;
class Card{
private String suit;
private int value;
public Card(String s,int v){
suit = s;
value = v;
}
public String getSuit(){
return suit;
}
public int getValue(){
return value;
}
public void display(){
System.out.println(value+"("+suit+")");
}
}
class Deck{
private ArrayList<Card> deck;
private ArrayList<Card> drawn;
public Deck(){
deck = new ArrayList<Card>();
drawn = new ArrayList<Card>();
String[] arr = {"Club","Spade","Heart","Diamond"};
for(String s : arr){
for(int i=1;i<=13;i++){
deck.add(new Card(s,i));
}
}
}
public void draw(){
drawn.add(deck.get(0));
deck.remove(0);
}
public void draw(int N){
if(N > deck.size()){
N = deck.size();
}
for(int i=0;i<N;i++){
draw();
}
}
public void showDrawn(){
for(Card c : drawn){
c.display();
}
}
public void shuffle(){
Collections.shuffle(deck);
}
public void restore(){
restore(drawn.size());
}
public void restore(int N){
if(N > drawn.size()){
N = drawn.size();
}
for(int i=0;i<N;i++){
deck.add(drawn.get(0));
drawn.remove(0);
}
}
public void showDeck(){
for(Card c : deck){
c.display();
}
}
}
class Test{
public static void main(String[] args){
Deck d = new Deck();
System.out.println("Original deck\n");
d.showDeck();
d.draw(8);
System.out.println("\nDeck after drawing 8 cards\n");
d.showDeck();
d.shuffle();
System.out.println("\nDeck after shuffling\n");
d.showDeck();
d.restore();
System.out.println("\nDeck after restoring cards\n");
d.showDeck();
}
}
