Java 案例之随机点名

代码：

import java.util.Random;
import java.util.Scanner;

public class Test03 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String students[] = new String[5];
        for (int i = 0;i < students.length;i++){
            System.out.print("第" + (i + 1) +"名同学的名字为：");
            students[i] = scanner.next();
        }

        for (int i = 0;i < students.length;i++){
            System.out.println("第" + (i + 1) + "个同学：" + students[i]);
        }

        int rand_num = new Random().nextInt(students.length);
        System.out.println("第点到名的同学是：" + students[rand_num]);
    }
}
