求教：下面的代码怎么无法输出扑克的值
//Card类
package com.imooc;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class Card {
private String color;
private String value;
private static final List<String> Colors = Arrays.asList("方块", "草花", "红桃","黑桃");
private static final List<String> Values = Arrays.asList("2", "3", "4", "5", "6", "7",
"8", "9", "10", "J", "Q", "K", "A");
public Card(String color, String value) {
super();
this.color = color;
this.value = value;
}
public Card() {
super();
// TODO Auto-generated constructor stub
}
//创建一副扑克
public static List<Card> generatePoker(){
//创建扑克集合
List<Card> pokerlist=new ArrayList<Card>();
//为扑克集合赋值
for(int i=0;i<4;i++){
String newColor=Colors.get(i);
for(int j=0;j<13;j++){
String newValue=Values.get(j);
Card newCard=new Card(newColor,newValue);
pokerlist.add(newCard);
}
}
return pokerlist;
}
}//playInitial类
package com.imooc;
import java.util.List;
public class playInitial {
private List<Card> cardList;
public playInitial() {
cardList=Card.generatePoker();
}
//显示创建的扑克的信息
public void showCardList(){
System.out.println(cardList.toString());
}
public static void main(String[] args) {
System.out.println("--------创建扑克--------");
playInitial pi=new playInitial();
pi.showCardList();
}
}输出结果：
--------创建扑克--------
