作业题又无答案

[soyen]

问题是：创建一存储若干随机整数的文本文件，文件名.整数个数和范围由键盘输入~
用JAVA编~帮个忙啊。。谢谢~

[soyen]

非常感谢啊

[火龙果被占用了]

这个是作业吗？是你在学习，还是别人在学习？自己做！

做好了，有问题再来问！

[soyen]

真的是作业啊。。
我编了一点，如下：
import java.io.*;
import java.util.*;
import java.util.Scanner;

class Random
{
static int s,t;
static float n;

public static void main(String[] args)throws IOException
{

String fileName="C:\\Hello.txt";
BufferedWriter writer=new BufferedWriter(new FileWriter(fileName));
System.out.println("请输入整数个数");
Scanner a=new Scanner(System.in);
int t=a.nextInt();
System.out.println("请输入范围");
Scanner b=new Scanner(System.in);
int s=b.nextInt();
for(int i=0;i<=t;i++)
{

n=(float)(Math.random()*s);

writer.write(n);
writer.newLine();
}
writer.close();
}
}
写文件名那部分，我不会，所以先这样，而且编译时，说writer.write(n)这里找不到符号。。
