This creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

Closing a ByteArrayOutputStream has no effect.

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

This method returns the current size of the buffer.

This method creates a newly allocated byte array.

This method converts the buffer’s contents into a string decoding bytes using the platform’s default character set.

This method converts the buffer’s contents into a string by decoding the bytes using the specified charsetName.

This method writes len bytes from the specified byte array starting at offset off to this byte array output stream.

This method Writes the specified byte to this byte array output stream.

This method writes the complete contents of this byte array output stream to the specified output stream argument, as if by calling the output stream’s write method using out.write(buf, 0, count).
