Java代码实现抽奖:从班级的学号中抽出一个一等奖,两个二等奖,三个三等奖
抽取问题, 重点是 同一个学号不能重复被抽取.解决办法很多,
比如数组可以使用下标来标记,号码是否被使用,使用了就继续下一次抽取
也可以使用集合来抽取,把集合顺序打乱,然后随便抽几个就可以了
参考代码:数组法
import java.util.Random;public class Test {
public static void main(String[] args) {
int stuNums=;
int[] nums=new int[stuNums];//存储学号的数组
boolean[] flags=new boolean[stuNums];//标记,用于标记对应下标的学号是否已经被抽取过了
for (int i = 0; i < stuNums; i++) {
nums[i]=i+1;//给学号赋值
}
Random r=new Random();
while(true){
int index = r.nextInt(stuNums);
if(!flags[index]){
System.out.println("A等:"+nums[index]);
flags[index]=true; //标记已经被使用过了
break;
}
}
for (int i = 0; i < 2; i++) {
int index = r.nextInt(stuNums);
if(!flags[index]){
System.out.println("B等:"+nums[index]);
flags[index]=true;
}else{
i--;//如果已经被抽取过了 ,那么i建议,再次循环
}
}
for (int i = 0; i < 3; i++) {
int index = r.nextInt(stuNums);
if(!flags[index]){
System.out.println("c等:"+nums[index]);
flags[index]=true;
}else{
i--;
}
}
}
}
集合法
import java.util.ArrayList;import java.util.Collections;
public class Test2 {
public static void main(String[] args) {
int stuNums=;
ArrayList<Integer> list=new ArrayList<Integer>();
for (int i = 0; i < stuNums; i++) {
list.add(i+1);
}
System.out.println("有序"+list);
Collections.shuffle(list);//打乱顺序
System.out.println("乱序"+list);
System.out.println("A等"+list.get(0));
System.out.println("B等"+list.get(1));
System.out.println("B等"+list.get(2));
System.out.println("C等"+list.get(3));
System.out.println("C等"+list.get(4));
System.out.println("C等"+list.get(5));
}
}
