Can we convert a byte array into an InputStream in Java?
There is a way to convert an array of bytes (byte[]) to InputStream in Java? I looked at some methods in Apache Commons IO, but found nothing.

Yes, I Googled and found it in a page before here. I was thinking was not a simple thing because I'm not much familiar with InputStream "family" – Renato Dinhani Mar 27 '12 at 20:55

1When you post a question, it gives you other questions with similar titles... I find it hard to believe that the question @TheNail posted (or one identical) wasn't listed – ggrigery Mar 27 '12 at 21:15

Maybe you want a [ByteArrayInputStream](http://docs.oracle.com/javase/6/docs/api/java/io/ByteArrayInputStream.html)? – Danny Mar 27 '12 at 20:49

ByteArrayInputStream extends InputStream:
InputStream myInputStream = new ByteArrayInputStream(myBytes);

Should be easy to find in the javadocs...
byte[] byteArr = new byte[] { 0xC, 0xA, 0xF, 0xE };
InputStream is = new ByteArrayInputStream(byteArr);
