How do I turn a String into a InputStreamReader in java? 6 answers

Like this:

InputStream stream = new ByteArrayInputStream(exampleString.getBytes(StandardCharsets.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.

For versions of Java less than 7, replace StandardCharsets.UTF_8 with "UTF-8" .

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, "UTF-8");

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.

您可以使用StringReader并将阅读器转换为使用此另一个计算器上的解决方案的输入流。
