2019-01-15 将文件1中的内容复制到文件2（缓冲流的使用）

public static void main(String[] args) {
        String path1="F:/info.txt";
        String path2="F:/2.txt";
        FileWriter fw=null;
        FileReader fr=null;
        BufferedWriter bw=null;
        BufferedReader br=null;
        try {
            fr=new FileReader(path1);
            fw=new FileWriter(path2);
            bw=new BufferedWriter(fw);
            br=new BufferedReader(fr);
            String line=null;
            while((line=br.readLine())!=null) {
                bw.write(line);
                bw.newLine();
            }
            bw.flush();
        }catch (Exception e) {
            // TODO: handle exception
        }
    }
