Java学习笔记_Day33(高级流)

缓冲流

1.字节缓冲流

原理：底层自带了长度为8129的缓冲区

BufferedInputStream bis=new BufferedInputStream(new FileInputStream("D:\\java\\myio\\a.txt"));
        BufferedOutputStream bos=new BufferedOutputStream(new FileOutputStream("D:\\java\\myio\\b.txt"));
        int b;
        while((b=bis.read())!=-1){
            bos.write(b);
        }

        bos.close();
        bis.close();

2.字符缓冲流

转换流

是字符流和字节流之间的桥梁
