In-Depth Information
The
ByteArrayOutputStream
class provides a dynamically growing
byte
ar-
ray to hold output. It adds constructors and methods:
public
ByteArrayOutputStream()
Creates a new
ByteArrayOutputStream
with a default initial array
size.
public
ByteArrayOutputStream(int size)
Creates a new
ByteArrayOutputStream
with the given initial ar-
ray size.
public int
size()
Returns the number of bytes generated thus far by output to
the stream.
public byte[]
toByteArray()
Returns a copy of the bytes generated thus far by output to
the stream. When you are finished writing into a
ByteArrayOut-
putStream
via upstream filter streams, you should flush the up-
stream objects before using
toByteArray
.
public void
reset()
Resets the stream to reuse the current buffer, discarding its
contents.
public String
toString()
Returns the current contents of the buffer as a
String
, trans-
lating bytes into characters according to the default character
encoding.
