Java: Convert String to InputStream

You can convert a Java String to InputStream using the ByteArrayInputStream class from the package.



public class JavaStringToInputStreamExample {
    public static void main(String[] args) throws IOException {

        String inputString = "This is a input string!";
        byte[] byteArr = inputString.getBytes();
        InputStream inputStream = new ByteArrayInputStream(byteArr);

        int nextByteData;
        while ((nextByteData = != -1) {
            System.out.print((char) nextByteData);


Note that you can also use StringBufferInputStream to achieve the same, but it has been deprecated since Java 1.1 and should be avoided.
