介绍

Java.io.BufferedOutputStream类实现一个缓冲的输出流。通过设置这样的输出流,应用程序可以将字节写入底层输出流,而不必为写入的每个字节引起对底层系统的调用。

类声明

以下是Java.io.BufferedOutputStream类的声明-

public class BufferedOutputStream
   extends FilterOutputStream

领域

以下是Java.io.BufferedOutputStream类的字段-

  • protected byte [] buf-这是存储数据的内部缓冲区。

  • protected int count-这是缓冲区中有效字节的数量。

  • protected OutputStream out-这是要过滤的基础输出流。

类的构造函数

Sr.No. Constructor & Description
1

BufferedOutputStream(OutputStream out)

This creates a new buffered output stream to write data to the specified underlying output stream.

2

BufferedOutputStream(OutputStream out, int size)

This creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

类方法

Sr.No. Method & Description
1 void flush()

This method flushes this buffered output stream.

2 void write(byte[] b, int off, int len)

This method writes len bytes from the specified byte array starting at offset off to this buffered output stream.

3 void write(int b)

This method writes the specified byte to this buffered output stream.
