Java: accessing a List of Strings as an InputStream

Question

Is there any way InputStream wrapping a list of UTF-8 String? I'd like to do something like:

InputStream in = new XyzInputStream( List<String> lines )

Answer 1

You can concatenate all the lines together to create a String then convert it to a byte array using String#getBytes and pass it into ByteArrayInputStream. However this is not the most efficient way of doing it.
