Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.
the initial size.
The buffer where data is stored.
The number of valid bytes in the buffer.
Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.
Increases the capacity if necessary to ensure that it can hold at least the number of elements specified by the minimum capacity argument.
the desired minimum capacity
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.
Increases the capacity to ensure that it can hold at least the number of elements specified by the minimum capacity argument.

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.
Returns the current size of the buffer.
the value of the count field, which is the number
of valid bytes in this output stream.
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.
the current contents of this output stream, as a byte array.
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))
the high byte of each resulting Unicode character.
the current contents of the output stream, as a string.
Converts the buffer's contents into a string by decoding the bytes using the specified {@link java.nio.charset.Charset 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 {@link java.nio.charset.CharsetDecoder} class should be used when more control over the decoding process is required.

String decoded from the buffer's contents.
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 {@linkplain java.nio.charset.CharsetDecoder} class should be used when more control over the decoding process is required.

Writes b.length bytes from the specified byte array

Writes the complete contents of this byte array output stream to

Generated using TypeDoc
This class implements an output stream in which the data is written into a byte array. The buffer automatically grows as data is written to it. The data can be retrieved using
toByteArray()andtoString().Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.
