Clear bytearrayoutputstream, need help

[redpois0n]

Hello. I am new here, I am pretty big on other forums, but this is new.

I have worked on java for around 1 year.

Now here is my error: I transfer file through socket, by first writing it to a bytearrayoutputstream.

byte[] buffer = new byte[(int)file.length()];
					        ByteArrayOutputStream ous = new ByteArrayOutputStream();
					        InputStream ios = new FileInputStream(file);
					        int read = 0;
					        while ( (read = ios.read(buffer)) != -1 ) {
					            ous.write(buffer, 0, read);
					        }
					        ous.flush();
					        byte[] ar = ous.toByteArray();
					        Connection.client.setSendBufferSize(ous.size());
				            Connection.client.getOutputStream().write(ar, 0, ous.size());
				            Connection.client.getOutputStream().flush();
					        ous.reset();
					        ous.close();
					        ios.close();
					        ios = null;
					        ar = null;
					        ous = null;
					        System.gc();

It writes OK and quick, but everything written to the bytearrayoutputstream stays there. Forever.

If I write a 50 mb file, the memory goes up 50 mb, and in the end, it goes outofmemory.

I will happily explain more if you dont understand.

TL;DR

Dispose of the object

Is this somehow related to Java sockets, everything written stays in memory - Stack Overflow and Java BufferedArrayOutputStream leaks in memory - Stack Overflow

nope.

everything written to the bytearrayoutputstream stays there. Forever.

Can you demonstrate that with a small simple program that compiles and executes?

Are you asking about data usage in an object
or about the JVM's memory usage.
