Java Learning Object-oriented poker (at the beginning)

Feelings:

At first do not understand or is not familiar with the characteristics of Java, do not know the relationship between classes and classes, Java encapsulation, inheritance, polymorphism and no better understanding, in the future learning process to master and familiar with Java development habits,

In the process of writing code, there are many things not mastered, relying on the help of teachers and classmates to complete this study, a preliminary understanding of Java object-oriented development of the basic essentials. Write this blog so that you can learn in the future, but also a good memory of it!

Above is a class diagram that represents the idea of writing this program.

Card class: His subordinate is CardView Superior is the player, has a certain relationship

Package Com.cqvie;
public class Card
{
public int rank,suit;
public int cardidx;
Public CardView CardView;
Public Player owner;
public Boolean selected=false;
public static String suits[]
=new string[]{"", "♠", "♥", "♣", "♦"};
public static String ranks[]
=new string[]{"J", "Q", "K", "A", "2", "Xiao Wang", "King"};

Public Card (int rank,int suit)
{
This.rank=rank; This.suit=suit;
This.cardview=new CardView (this); To generate the CardView object synchronously when the card object is generated
}
Public String toString ()
{
if (rank<=10)//10 pips or less
return Suits[suit]+rank;
else//over 10 pips
return suits[suit]+ ranks[rank-11];
}
}
