--------------------------
void flush()
* 刷新此缓冲的输出流。
void write(byte[] b);
* 写入整个字节数组
void write(byte[] b, int off, int len)

# 文件字节流输出的 Buffer 装饰流,带缓冲区的,可以提高效率
FileOutputStream fileOutputStream = new FileOutputStream("E:\\IOTEST.java");
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(fileOutputStream,1024);
bufferedOutputStream.write(new String("余文朋").getBytes());
bufferedOutputStream.flush();
bufferedOutputStream.close();
