Java实现抽奖算法的示例代码_java

public class Basics28 {
public static void main(String[] args) {
List luckUserNames = getLuckUserNames();
Random random = new Random();
int luckNum = random.nextInt(6);
System.out.println("幸运的未来大佬是："+luckUserNames.get(luckNum));
}
private static List getLuckUserNames(){
List luckUserNames = new ArrayList();
luckUserNames.add("李慢慢_");
luckUserNames.add("TryAgain-");
luckUserNames.add("team_dog");
luckUserNames.add("Jasonakeke");
luckUserNames.add("学好c语言的小王同学");
luckUserNames.add("Ara～追着风跑");
return luckUserNames;
}
}


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