Jun 24, 2020 · Output:-From the output, you can see that the Stream Reader read both the lines from the file. Finally, the lines of the string read from the stream were sent to the Console. Stream Writer. The stream writer is used to write data to a file using streams. The data from the application is first written into the stream. Example program. Consider this program. It uses a MemoryStream and we want to write 5 million bytes to it. But we wrap the MemoryStream in a BufferedStream. And: We call WriteByte on the BufferedStream, which acts upon the MemoryStream. But it buffers operations. 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. File Input/Output operations consume a lot of important resources and are time consuming. Hence, reading a chunk of bytes out of a file and storing it in a local buffer for later processing is faster and than reading a byte at a time, out of a file.
Java BufferedOutputStream Class for beginners and professionals with examples on Java IO or Input Output in Java with input stream, output stream, reader and writer class. The java.io package provides api to reading and writing data.

Unbuffered Output Streams: FileOutputStream, OutputStreamWriter, FileWriter. Buffered Output Streams: PrintStream, PrintWriter. In addition, we have the BufferedInputStream, BufferedOutputStream, BufferedReader and BufferedWriter streams to convert the unbuffered streams into buffered versions. The BufferedOutputStream class is a subclass of FilterOutputStream that stores written data in an internal buffer (a protected byte array field named buf) until the buffer is full or the stream is explicitly flushed using the flush ()method. /** * Copy from an input stream to a file (and buffer it) and close the input stream. *
* It is highly recommended to use FileUtils.retryCopy whenever possible, and not use a raw `InputStream` * * @param is The input stream to copy bytes from. `is` is closed regardless of the copy result. * @param file The file to copy bytes to.
