ByteArrayOutputStream class methods in java

java.io.ByteArrayOutputStream

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.

Note:

The data can be retrieved using toByteArray() and toString().

Some methods of ByteArrayOutputStream class.

close(): This method closes a ByteArrayOutputStream.

reset(): This method resets the count field of this ByteArrayOutputStreamto zero so that all currently accumulated output in the output stream is discarded

size(): This method returns the current size of the buffer.

toByteArray(): This method creates a newly allocated byte array.

toString(): This method converts the buffer's contents into string decoding bytes using the platform's default character set.

toString(String): This method converts the buffer's contents into a string by decoding the bytes using the named charset.

write(int): This method writes the specified byte to this ByteArrayOutputStream.

write(byte[], int, int): This method writes len bytes from the specified byte array starting at offset off to this ByteArrayOutputStream.

writeBytes(byte[]): This method writes the complete contents of the specified byte array to this ByteArrayOutputStream.
