纯随机数发生器--动手动脑

 

代码

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

public class TestSeed
{
    public static void main(String[] args)
 {
      
        Random r = new Random(System.currentTimeMillis());
        System.out.println("请输入要得到多少随机数");
        int m;
        Scanner in = new Scanner(System.in);
        m = in.nextInt();
        for(int i=0;i<m;i++)
         System.out.println( r.nextInt());
       
    }
