Question

Java随机抽取人名完整代码

Answer 1

public class test {
public static void main(String[] args) {
//定义人名数组
String [] name = {"张三","李四","王五","八神庵","不知火舞","大蛇","景天","唐雪见","李逍遥","赵灵儿"};
//随机生成数组下标、
int num = (int)(Math.random() * 1000);
//对生成的随机数进行判断，如果小于数组下标，就跳出循环
while (num>name.length-1) {
if (num<=name.length-1) {
break;
}
num = (int)(Math.random() * 1000);
}
//将数组下标设置成随机数，就可以实现人名的随机抽取
System.out.println(“被抽到的同学是：”+name[num]);
}
}
