Closing a ByteArrayOutputStream has no effect.

  Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

  Flushes this output stream and forces any buffered output bytes to be written out.

  Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.

The flush method of OutputStream does nothing.
Throws:
- IOException - if an I/O error occurs.

  Resets the count field of this byte array output stream to zero, so that all currently accumulated output in the output stream is discarded.

  Resets the count field of this byte array output
stream to zero, so that all currently accumulated output in the
output stream is discarded. The output stream can be used again,
reusing the already allocated buffer space.
See Also: ByteArrayInputStream.count,

  Returns the current size of the buffer.

  Returns the current size of the buffer.
Returns: the value of the count field, which is the number of valid bytes in this output stream.
See Also: ByteArrayOutputStream.count,

  Creates a newly allocated byte array.

  Creates a newly allocated byte array. Its size is the current
size of this output stream and the valid contents of the buffer
have been copied into it.
Returns: the current contents of this output stream, as a byte array.
See Also: ByteArrayOutputStream.size(),

  Converts the buffer's contents into a string decoding bytes using the platform's default character set.

  Converts the buffer's contents into a string decoding bytes using the platform's default character set. The length of the new String is a function of the character set, and hence may not be equal to the size of the buffer.

This method always replaces malformed-input and unmappable-character sequences with the default replacement string for the platform's default character set. The CharsetDecoder class should be used when more control over the decoding process is required.
Returns: String decoded from the buffer's contents.
Since: JDK1.1

  Creates a newly allocated string.

  Creates a newly allocated string. Its size is the current size of
the output stream and the valid contents of the buffer have been
copied into it. Each character c in the resulting string is
constructed from the corresponding element b in the byte
array such that:

     c == (char)(((hibyte & 0xff) << 8) | (b & 0xff))
 

Returns: the current contents of the output stream, as a string.
Parameters:
- hibyte - the high byte of each resulting Unicode character.
See Also: ByteArrayOutputStream.size(), ByteArrayOutputStream.toString(String), ByteArrayOutputStream.toString(),

  Converts the buffer's contents into a string by decoding the bytes using the specified charsetName.

  Converts the buffer's contents into a string by decoding the bytes using the specified charsetName. The length of the new String is a function of the charset, and hence may not be equal to the length of the byte array.

This method always replaces malformed-input and unmappable-character sequences with this charset's default replacement string. The CharsetDecoder class should be used when more control over the decoding process is required.
Returns: String decoded from the buffer's contents.
Parameters:
- charsetName - the name of a supported {@linkplain java.nio.charset.Charset charset}
Throws:
- UnsupportedEncodingException - If the named charset is not supported
