Java 轻松掌握字符缓冲流的使用

public class BufferedWriteReaderDemo {
    public static void main(String[] args) throws IOException {
        //使用字符缓冲流实现一个文件的复制
        //使用子类FileWrite\FileReader替代OutputStreamWrite\InputStreamReader
        BufferedReader br=new BufferedReader(new FileReader("E:\\abc.txt"));
        BufferedWriter bw=new BufferedWriter(new FileWriter("F:\\abcdef.txt"));
        //读取数据
//        int len;
//        while ((len=br.read())!=-1){
//            bw.write(len);
//        }
        int len;
        char[] ch=new char[1024];
        while ((len=br.read(ch))!=-1){
            bw.write(ch);
        }
        //释放资源
        br.close();
        bw.close();
    }
}

public class Demo02 {
    public static void main(String[] args) throws IOException {
        //字符缓冲流特有方法实现复制Java文件
        BufferedReader br=new BufferedReader(new FileReader("E:\\abc.txt"));
        BufferedWriter bw=new BufferedWriter(new FileWriter("F:\\aaa.txt"));
        //读写数据
        String line;
        while ((line=br.readLine())!=null){
            bw.write(line);
            bw.newLine();//换行
            bw.flush();//刷新缓存区
        }
       
        //释放资源
        br.close();
        bw.close();
    }
