Java.io.BufferedOutputStream class in Java
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:
import java.io.*;
class BufferedOutputStreamDemo
{
public static void main(String args[]) throws Exception
{
FileOutputStream fout = new FileOutputStream( "f1.txt" );
BufferedOutputStream bout = new BufferedOutputStream(fout);
for ( int i = 65 ; i < 75 ; i++)
{
bout.write(i);
}
byte b[] = { 75 , 76 , 77 , 78 , 79 , 80 };
bout.write(b);
bout.flush();
bout.close();
fout.close();
}
}
