关于javaIo流的权限不够问题

package com05;

import java.io.*;

public class Byte8 {
    public static void main(String[] args) throws IOException {
        //可以操作文本文件哦
           BufferedInputStream bufferedInputStream = new BufferedInputStream(new FileInputStream("D:\\IDEA\\java\\lujiajian\\text.txt"));
    BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(new FileOutputStream("D:\\IDEA\\java\\lujiajian\\src\\com05\\text3.txt"));
    byte[] bytes = new byte[1024];                                                 //FileInputStream\FileOutputStream节点流
    int i=0;                                                                              //文件名一定要带不然会提示权限不够text3.txt。复制文件要带文件名
        while ((i=bufferedInputStream.read(bytes))!=-1){//文件读取完毕i会是-1
                bufferedOutputStream.write(bytes,0,i);//如果不写-1会一直复制到时候盘符就会满。什么文件要带什么后椎名.txt  .jpg
        }
        bufferedInputStream.close();
        bufferedOutputStream.close();
    }
}

1.复制的文件名不写会出现权限问题

2.复制文件在c盘会出现权限问题
