1. Java隨機抽取人名完整代碼
public class test {
public static void main(String[] args) {
//定義人名數組
String [] name = {"張三","李四","王五","八神庵","不知火舞","大蛇","景天","唐雪見","李逍遙","趙靈兒專"};
//隨機生成數組下標、
int num = (int)(Math.random() * 1000);
//對生成的屬隨機數進行判斷，如果小於數組下標，就跳出循環
while (num>name.length-1) {
if (num<=name.length-1) {
break;
}
num = (int)(Math.random() * 1000);
}
//將數組下標設置成隨機數，就可以實現人名的隨機抽取
System.out.println(「被抽到的同學是：」+name[num]);
}
}
