谁能解释一下这个java代码是如何工作的？

Question

import java.util.Random;

public class Rand {
    public static void main(String args[]) {
        Random ran = new Random();
        int number = ran.nextInt(9) + 1;
        number *= 10000;
        number += ran.nextInt(10000);
        System.out.println("Random no:" + number);
    }
}

Answer 1

它有什么神秘之处？

public static void main(String args[])
{
    Random ran = new Random();

    //Generate a digit between 0-8 +1
    int number = ran.nextInt(9) + 1;
    //Multiply with 10000
    number *= 10000;
    //Add a number between 0-9999
    number += ran.nextInt(10000);

    System.out.println("Random no:" + number);
}

在你提出要求之前，你应该获得一些基础知识 - 或者至少试着自己解决问题。
