How do I copy an object in Java?

Question

Consider the code below:

DummyBean dum = new DummyBean();
dum.setDummy(\"foo\");
System.out.println(dum.getDummy()); // prints \'foo\'

DummyBean dumtwo = du         


        

Answer 1

Pass the object that you want to copy and get the object you want:

private Object copyObject(Object objSource) {
        try {
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            ObjectOutputStream oos = new ObjectOutputStream(bos);
            oos.writeObject(objSource);
            oos.flush();
            oos.close();
            bos.close();
            byte[] byteData = bos.toByteArray();
            ByteArrayInputStream bais = new ByteArrayInputStream(byteData);
            try {
                objDest = new ObjectInputStream(bais).readObject();
            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return objDest;

    }

Now parse the objDest to desired object.

Happy Coding!
