Methods

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.

Parameters:
b - the byte
Throws: IOException

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.
o flush 
 public abstract void flush() throws IOException
