o flush()
Flushes the stream.
o write(int)
Writes a byte.
o write(byte[])
Writes an array of bytes.
o write(byte[], int, int)
Writes a sub array of bytes.
o writeObject(Object)
Write an object to the underlying storage or stream.

Methods

o close 
public abstract void close() throws IOException
Closes the stream. This method must be called to release any resources associated with the stream.

Throws: IOException
If an I/O error has occurred.
Since:
JDK1.1
o flush 
public abstract void flush() throws IOException
Flushes the stream. This will write any buffered output bytes.

Throws: IOException
If an I/O error has occurred.
Since:
JDK1.1
o write 
public abstract void write(int b) throws IOException
Writes a byte. This method will block until the byte is actually written.

Parameters:
b - the byte
Throws: IOException
If an I/O error has occurred.
Since:
JDK1.1
o write 
public abstract void write(byte b) throws IOException
Writes an array of bytes. This method will block until the bytes are actually written.

Parameters:
b - the data to be written
Throws: IOException
If an I/O error has occurred.
Since:
JDK1.1
o write 
public abstract void write(byte b,
                           int off,
                           int len) throws IOException
Writes a sub array of bytes.

Parameters:
b - the data to be written
off - the start offset in the data
len - the number of bytes that are written
Throws: IOException
If an I/O error has occurred.
Since:
JDK1.1
o writeObject 
public abstract void writeObject(Object obj) throws IOException
Write an object to the underlying storage or stream. The class that implements this interface defines how the object is written.

Throws: IOException
Any of the usual Input/Output related exceptions.
