How do I turn a String into a Stream in java?

Question

I need to transform a string into (finally) an InputStreamReader. Any ideas?

Answer 1

Does it have to be specifically an InputStreamReader? How about using StringReader?

Otherwise, you could use StringBufferInputStream, but it's deprecated because of character conversion issues (which is why you should prefer StringReader).

Answer 2

ByteArrayInputStream also does the trick (since Java 1.4)

InputStream is = new ByteArrayInputStream( myString.getBytes( charset ) );

Answer 3

Same question as @Dan - why not StringReader ?

If it has to be InputStreamReader, then:

String charset = ...; // your charset
byte[] bytes = string.getBytes(charset);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
InputStreamReader isr = new InputStreamReader(bais);

Answer 4

Cool , thank you very much. I also found the apache commons IOUtils class , so :

InputStreamReader isr = new InputStreamReader(IOUtils.toInputStream(myString));

Answer 5

Hi,

If you know that the String is in UTF-8 you could use alternatively:

InputStream is = com.sun.xml.internal.ws.util.xml.XmlUtil.getUTF8Stream(myString);
