你指的是Card里的toString方法吧

public String toString() {
String aa = suit + " " + num + " ";
return aa;
}
toString这个方法一般在 System.out.print时使用，这个是打印出String，JVM就是默认调用类的toSting方法
注：所有类都有toString方法，默认是当前对象的hashcode，即内存地址
所以在发牌是打印
public void dealcard()//发牌
{
for(int i=0;i52;i++)
{
if(i%4==0i!=0){
System.out.println(); //每发4张牌输出换行
}
// 就是这里，默认调用card的toString方法
System.out.print(card[i]); //依次输出 发的牌
}
}

}
1.定义牌类
public class Card{
public int id;//牌大小
public String number;//牌值名称
public String color;//花色
}
2.定义牌组,用ArrayList存放所有牌
ArrayListCard cardGroup =new ArrayListCard();
3.定义花色枚举
public static final String[] COLORS=new String[]{"方块","梅花","红桃","黑桃"};
4.定义牌值大小枚举
public static fina String[] CARDVALUES=new String[]{"A","1","2","3",
"4","5","6","7","8","9","10","J","Q","K","King_Small","King_Big"};
5.初始化牌组,这就是一副新牌，没切过，己经排好序的
public void initCardGroup(){
//加入A~K
for(int i=0;i13;i++){
for (int j=0;j4;j++){
//生成一张牌的对象
Card card=new Card();
card.id=i;
card.color=COLORS[j];
card.munber=CARDVALUES[i];
//将对象加入牌组
cardGroup.add(card);
}
}
//加入大小王
Card card_k1=new Card();
card_k1.id=13;
card_k1.color="King_Small";
card_k1.number="King_Small";
cardGroup.add(card_k1);
Card card_k2=new Card();
card_k2.id=14;
card_k2.color="King_big";
card_k2.number="King_big";
cardGroup.add(card_k2);
}
6. 洗牌，将原牌组打乱，得到新的牌组
public ArrayListCard flushCardsGroup(ArrayListCard src){
ArrayListCard result=new ArrayListCard();
while(src.size0){
int size=src.size();
//以size为限，生成0~size之间的随机数
Random r=new Random();
int index=r.nextInt(size);
//对index做个检查
if(index0){index=0;}
if(indexsize-1){index=size-1;}
//index就是捡出来的牌，加到新的数组中，从原来数组中删除
Card card=src.get(index);
result.add(card);
card.remove(index);
}
return result;
}
估计需要使用多线程，每一次在一段时间内，设置标签位置，重绘。
