Buffered output stream example xmoux

To reduce this kind of overhead, the Java platform implements buffered I/O streams. Buffered input streams read data from a memory area known as a buffer; the native input API is called only when the buffer is empty. Similarly, buffered output streams write data to a buffer, and the native output API is called only when the buffer is full. Oct 29, 2014 · Buffered Streams are used to speed up the input output operations by simply creating a buffer space of some specific size so that we don’t have to access the disk every time we perform I/O operation, which is a time and resource consuming process. In absence of buffer storage each I/O operation is handled by the operating system. Example: OutputStreamWriter output = new OutputStreamWriter(fileObj,"UTF-8"); Here charset Name that is being used for conversion of a character stream to byte stream is “UTF-8”. Methods. 1. close():- This method helps to close the stream after flushing it. No Parameter is required and nothing is returned from this method. Jul 10, 2005 · In general, ofstreams are buffered. You can make a stream unbuffered by invoking setbuf(0,0). For example, ofstream of; of.setbuf(0,0); // makes it unbuffered. You can force a buffered stream to flush the contents using std::endl. Other interesting thing is to tie an buffered output stream with a buffered input stream.

OutputStream OutputStream class is a base class of all the classes that are used to write bytes to a file, memory or console. OutputStream is an abstract class and hence we can't create its object but we can use its subclasses for writing bytes to the output stream.

BufferedOutputStream(OutputStream out) - Creates a new buffered output stream to write data to the specified underlying output stream. BufferedOutputStream(OutputStream out, int size) - Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size. BufferedOutputStream class Methods

The following code shows how to read and write with buffered stream. Example / / f r o m w w w. j a v a 2 s. c o m using System; using System.IO; class BufStreamApp The BufferedOutputStream class of java.io package, the 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. Standard output is a stream to which a program writes its output data. The program requests data transfer with the write operation. Not all programs generate output. For example, the file rename command (variously called mv, move, or ren) is silent on success. Unless redirected, standard output is inherited from the parent process. Likewise, an output stream must not have more than one buffered wrapper because multiple wrappers can cause multiple output strings to be output in an unexpected order. For example, the javax.servlet.ServletResponse allows for the creation of a PrintWriter or an OutputStream to hold the response generated by a web servlet.
