public void open(AudioFormat format, int bufferSize) throws LineUnavailableException
The buffer size is specified in bytes, but must represent an integral
number of sample frames. Invoking this method with a requested buffer
size that does not meet this requirement may result in an
IllegalArgumentException. The actual buffer size for the open line may
differ from the requested buffer size. The value actually set may be
queried by subsequently calling DataLine#getBufferSize.
If this operation succeeds, the line is marked as open, and an
LineEvent.Type#OPEN OPEN event is dispatched to the
line's listeners.
Invoking this method on a line which is already open is illegal
and may result in an IllegalStateException.
Note that some lines, once closed, cannot be reopened. Attempts
to reopen such a line will always result in a
LineUnavailableException.

The implementation chooses a buffer size, which is measured in bytes but
which encompasses an integral number of sample frames. The buffer size
that the system has chosen may be queried by subsequently calling
DataLine#getBufferSize.
If this operation succeeds, the line is marked as open, and an
LineEvent.Type#OPEN OPEN event is dispatched to the
line's listeners.
Invoking this method on a line which is already open is illegal
and may result in an IllegalStateException.
Note that some lines, once closed, cannot be reopened. Attempts
to reopen such a line will always result in a
LineUnavailableException.

DataLine#available available),
this method blocks until the requested amount of data has been written.
This applies even if the requested amount of data to write is greater
than the data line's buffer size. However, if the data line is closed,
stopped, or flushed before the requested amount has been written,
the method no longer blocks, but returns the number of bytes
written thus far.
The number of bytes that can be written without blocking can be ascertained
using the DataLine#available available method of the
DataLine interface. (While it is guaranteed that
this number of bytes can be written without blocking, there is no guarantee
that attempts to write additional data will block.)
The number of bytes to write must represent an integral number of
sample frames, such that:
[ bytes written ] % [frame size in bytes ] == 0IllegalArgumentException.write in interface SourceDataLineb - a byte array containing data to be written to the data lineoff - the offset from the beginning of the array, in byteslen - the length, in bytes, of the valid data in the array
