How do I convert a String to an InputStream in Java?

Given a string:

String exampleString = "example";

How do I convert this to an InputStream?

From stackoverflow

• Like this:

  InputStream stream = new ByteArrayInputStream(exampleString.getBytes("UTF-8"));
  

  Note that this assumes that you want an InputStream that is a stream of bytes that represent your original string encoded as UTF-8.

• You could use a StringReader and convert the reader to an input stream using the solution in this other stackoverflow post.

• I find that using Apache Commons IO makes my life much easier.

  String source = "This is the source of my input stream";
  InputStream in = IOUtils.toInputStream(source);
  

  You may find that the library also offer many other shortcuts to commonly done tasks that you may be able to use in your project.
