Question

Is there a (better) way to dynamically create Objects?

Right now I’m using a simple ‘factory pattern’ solution as following:

   String classType = generalObject.getClass().toString();

    if(classType.equals("class be.testApp.UserObject")) {
        return UserObject.fromByteArray(data);
//return new UserObject();
    }
    else if(classType.equals("class.be.testApp.NewsObject"))    {
        return NewsObject.fromByteArray(data);
//return new NewsObject();      
    }

This code is not a factory pattern and no object is created. You evaluate the class name and call a static method on a class.

Now it looks like you have an object (generalObject) and want to create a new instance of the very same type. If all possible types have a public default constructor (convention!), then you can use this to create a new instance based on the given object:

Object newObject = generalObject.getClass().newInstance();

(but maybe I still didn’t get your idea…)
