class CardTest{
public static void main(String[] args){

Card c0 = fpj.getCard();
Card c1 = fpj.getCard();
Card c2 = fpj.getCard();
Card[] cards = new Card[3];
cards[0] = c0;

for( int x=0; x<cards.length; x++){
System.out.println(cards[x].getHuase()+""+cards[x].getDianshu()+"");
}
}
}
class Card {
//成员变量
String huase;//花色
int dianshu;//点数
//构造方法
Card(){}
Card(String huase, int dianshu){
this.huase = huase;
this.dianshu = dianshu;
}
public String getHuase(){
return huase;
}
public int getDianshu(){
return dianshu;
}
}
class FaPaiJi {
// 成员方法
// 返回值类型
// 参数列表
public Card getCard(){
//创建对象 String[] hs = {"黑桃","梅花","方块","红桃"};
Random r = new Random();
int x = r.nextInt(4);
String huase = hs[x];
Card card = new Card(huase,dianshu);
return card;
}
}
输出结果可能出现相同项，怎样解决这个问题？
/*
生成牌的时候，直接生成52不一样的牌
随机 Random().nextInt(52),返回的是 0--51
只要随机数不一样
*/ Random r = new Random();
int x1 = r.nextInt(13)+1;
int x2 = r.nextInt(13)+14;
int x3 = r.nextInt(13)+27;
int x4 = r.nextInt(13)+40;
String[][] hs = {"黑桃","梅花","方块","红桃"};
后面怎么做？求解
public class D {
public static void main(String[] args) {
ArrayList<String> array = new ArrayList<String>();
// 定义一个花色数组
String[] colors = { "♠", "♥", "♣", "♦" };
// 定义一个点数数组
String[] numbers = { "A", "2", "3", "4", "5", "6", "7", "8", "9", "10","J", "Q", "K" };
for (String color : colors) {
for (String number : numbers) {
array.add(color.concat(number));
}
}
// 洗牌
Collections.shuffle(array);
for (int i = 0; i < 3; i++) {
System.out.println(array.get(i));
}
}
