Java.io.BufferedInputStream class in Java
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.
Fields
- protected byte[] buf: The internal buffer where data is stored.
- protected int count: The number of valid bytes in the buffer.
Constructor and Description
- 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.
Methods:
-
void flush() : Flushes this buffered output stream.
Syntax :public void flush() throws IOException Overrides: flush in class FilterOutputStream Throws: IOException
-
void write(byte[] b, int off, int len) : Writes len bytes from the specified byte array starting at offset off to this buffered output stream.
Syntax : Parameters: b - the data. off - the start offset in the data. len - the number of bytes to write. Throws: IOException
-
void write(int b) : Writes the specified byte to this buffered output stream.
Syntax : Parameters: b - the byte to be written. Throws: IOException
Program:
//Java program demonstrating BufferedOutputStream import java.io.*;
class BufferedOutputStreamDemo
{ public static void main(String args[]) throws Exception
{
FileOutputStream fout = new FileOutputStream( "f1.txt" );
//creating bufferdOutputStream obj
BufferedOutputStream bout = new BufferedOutputStream(fout);
//illustrating write() method
for ( int i = 65 ; i < 75 ; i++)
{
bout.write(i);
}
byte b[] = { 75 , 76 , 77 , 78 , 79 , 80 };
bout.write(b);
//illustrating flush() method
bout.flush();
//illustrating close() method
bout.close();
fout.close();
}
