Java数组实现的简单点名器
用数组将名单存储，然后调用Random函数取随机数实现随机点名。

代码实现

import java.util.Random;public class DianMingDemo {public static void main(String[] args) {//点名器  数组存储名字String[] name = {"小李","小2","小3","小4","小5","小6","小7","小8","小9","小10","小11"};Random random = new Random();  //获取随机数int i = random.nextInt(11)+1;System.out.println(name[i]);}
}
