Is it necessary to close ByteArrayOutputStream?

Is it necessary to close ByteArrayOutputStream?

It is just unnecessary. It is often necessary to close an output pipeline that ends in a ByteArrayOutputStream , but this is not because of memory usage or GC considerations. Memory is used (at least) as long as the ByteArrayOutputStream object is reachable.

How do you write data to ByteArrayOutputStream?

Methods of ByteArrayOutputStream

2. write(byte[] array) – writes the bytes from the specified array to the output stream.

Do we need to close ByteArrayInputStream?

You don’t have to close ByteArrayInputStream , the moment it is not referenced by any variable, garbage collector will release the stream and somebytes (of course assuming they aren’t referenced somewhere else).

Do we need to close OutputStream in Java?

close() method closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened. The close method of OutputStream does nothing.

What is difference between ByteArrayOutputStream and FileOutputStream?

Which method is used by ByteArrayOutputStream class?
