when written to. It is intended to be used in the same manner as
/dev/null. None of this class's methods do anything at all.
void | close()- This method closes the stream.
|
void | flush()- This method forces any data that may have been buffered to be written
to the underlying output device.

void | write(b[] )
|
void | write(b[] , int off, int len)
|

NullOutputStream
public NullOutputStream()
This is the default no-argument constructor for this class. This method
does nothing in this class.
close
public void close()
This method closes the stream. Any internal or native resources
associated with this stream are freed. Any subsequent attempt to
access the stream might throw an exception.
This method in this class does nothing.
- close in interface Closeable
- close in interface AutoCloseable
- close in interface OutputStream
flush
public void flush()
This method forces any data that may have been buffered to be written
to the underlying output device. Please note that the host environment
might perform its own buffering unbeknowst to Java. In that case, a
write made (for example, to a disk drive) might be cached in OS
buffers instead of actually being written to disk.
This method in this class does nothing.
- flush in interface Flushable
- flush in interface OutputStream
write
public void write(b[] )
write
public void write(b[] ,
int off,
int len)
write
public void write(int b)
This method writes a single byte to the output stream. The byte written
is the low eight bits of the
int passed and a argument.
Subclasses must provide an implementation of this abstract method
- write in interface OutputStream
b - The byte to be written to the output stream, passed as
the low eight bits of an int
