How can I convert an Object to Inputstream

Question

How can I convert the java Object into a InputStream?

Answer 1

You can use ObjectOutputStream

You write the object (obj in the code below) to the ObjectOutputStream, your object you want to convert to an input stream must implement Serializable.

---

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ObjectOutputStream oos = new ObjectOutputStream(baos);


    oos.writeObject(obj);

    oos.flush();
    oos.close();

    InputStream is = new ByteArrayInputStream(baos.toByteArray());
