Can we convert a byte array into an InputStream in Java?

Question

Can we convert a byte array into an InputStream in Java? I have been looking on the internet but couldn't find it.

I have a method that has an InputStream as argument.

The InputStream cph I have is base64 encoded so I had to decode it using

BASE64Decoder decoder = new BASE64Decoder();
byte[] decodedBytes = decoder.decodeBuffer(cph);

Now how do I convert decodedBytes again to InputStream?

java.io.ByteArrayInputStream extends InputStream to do exactly this:

InputStream myInputStream = new ByteArrayInputStream(myBytes);

It is in the javadocs:

byte[] byteArr = new byte[] { 0xC, 0xA, 0xF, 0xE };
InputStream is = new ByteArrayInputStream(byteArr);
