1.BufferedInputStream使用

public class BufferedInputStreamDemo01 {
    public static void main(String[] args) throws Exception {

        //1创建字节输入缓冲流

        FileInputStream fis = new FileInputStream("C:\\Users\\Public\\Documents\\aaa.txt");

        BufferedInputStream bis = new BufferedInputStream(fis);

        //读取文件内容
        int data;
        while ((data = bis.read()) != -1){
            System.out.print((char) data);
        }

        //关闭通道
        bis.close();
        System.out.println("执行完毕");
    }

2.BufferedOutputStream使用

public class BufferedOutputStreamDemo01 {
    public static void main(String[] args) throws Exception {

        //1.创建字节输出缓冲流对象

        FileOutputStream fos = new FileOutputStream("C:\\Users\\Public\\Documents\\eee.txt",true);
        BufferedOutputStream bos = new BufferedOutputStream(fos);

        //2写入文件

        for (int i = 0; i < 10; i++) {
            bos.write("HelloWorld\n\r".getBytes());//先写入到自带的8K缓冲区中
            bos.flush();//从缓冲区刷新到硬盘
        }

        //关闭通道
        bos.close();
        System.out.println("执行完毕");

    }
}
