If you have a object, how should you process that object and produce a String?

Suppose I have an InputStream that contains text data, and I want to convert it to a String, so, for example, I can write that to a log file.

What is the easiest way to take the InputStream and convert it to a String?

public String convertStreamToString(InputStream is) {

    // ???

A right way to do this is applying Apache commons IOUtils to copy the InputStream within a StringWriter... something like

StringWriter writer = new StringWriter();

IOUtils.copy(inputStream, writer, encoding);

String theString = writer.toString();


// NB: does not close inputStream, you'll have to use try-with-resources for that

String theString = IOUtils.toString(inputStream, encoding); 

Alternatively, you could apply ByteArrayOutputStream if you don't want to tangle your Streams and Writers
