Methods

o write 
public abstract void write(int b) throws IOException
Writes a byte. Will block until the byte is actually written.
Parameters:
b - the byte to be written
Throws: IOException
If an I/O error has occurred.
o write 
public abstract void write(byte b[]) throws IOException
Writes an array of bytes.
Parameters:
b - the data to be written
Throws: IOException
If an I/O error has occurred.
o write 
public abstract void write(byte b[],
                             int off,
                             int len) throws IOException
Writes a subarray 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.
