Java.io.BufferedOutputStream Class
Introduction
The Java.io.BufferedOutputStream class implements a buffered output stream. By setting up such an output stream, an application can write bytes to the underlying output stream without necessarily causing a call to the underlying system for each byte written.
Class declaration
Following is the declaration for Java.io.BufferedOutputStream class −
public class BufferedOutputStream
extends FilterOutputStream
Field
Following are the fields for Java.io.BufferedOutputStream class −
protected byte[] buf − This is the internal buffer where data is stored.
protected int count − This is the number of valid bytes in the buffer.
protected OutputStream out − This is the underlying output stream to be filtered.
