I have a String[] array and I need to convert it to InputStream.

I've seen Byte[] -> InputStream and String -> InputStream, but not this. Any tips?

An InputStream of what? Delimited? Length-prefixed? –  SLaks Sep 22 '13 at 23:30

An InputStream is for binary, perhaps you wanted a Reader which is for text? –  Peter Lawrey Sep 22 '13 at 23:31
    
Actually, either will do, but I arbitrarily chose to ask about InputStream. –  Walrus the Cat Sep 22 '13 at 23:34

You can construct a merged String with some separator and then to byte[] and then to ByteArrayInputStream.

Here's a way to convert a String to InputStream in Java.

Yeah... that's the way I was going to go... zip up an array of newlines with my string array and join to a string... but I was hoping there was a more direct route. –  Walrus the Cat Sep 22 '13 at 23:34

Have a look at the following link: http://www.mkyong.com/java/how-to-convert-string-to-inputstream-in-java/

However, the difference in the code is that you should concatenate all the strings together in one string before converting. 

 String concatenatedString = ... convert your array

        // convert String into InputStream
        InputStream is = new ByteArrayInputStream(str.getBytes());

        // read it with BufferedReader
        BufferedReader br = new BufferedReader(new InputStreamReader(is));

        String line;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }

        br.close();

I'll take it from your answer, as well as kocko's, that there is no direct route from what I need to what I have. Thx –  Walrus the Cat Sep 22 '13 at 23:35
