编写程序，使用FileReader和FileWriter及缓冲流完成对某个文件的复制。（如将file1.txt的内容复制给file2.txt）

 

import java.io.*;
public class FileDemo {
    public static void main(String[] args) throws IOException {
        //file1里写入abcd
        BufferedReader br=new BufferedReader(new FileReader("C:\\Users\\略略略\\IdeaProjects\\out\\test8_2\\src\\file1.txt"));
        BufferedWriter bf=new BufferedWriter(new FileWriter("C:\\Users\\略略略\\IdeaProjects\\out\\test8_2\\src\\file2.txt"));
        String str= br.readLine();
        bf.write(str);
        br.close();
        bf.close();
    }
}
