Type.GetType() equivalent

Use Object.getClass() or instanceof

Activator.CreateInstance() equivalent

If a class has a no-argument constructor, then creating an object from its package-qualified class name is usually done using using Class.forName and Class.newInstance like below 

 Class clazz = Class.forName("test.Demo");
 Demo demo = (Demo) clazz.newInstance();

If class dosent have no-argument constructor you must use Reflection like below

Class<?> clazz = Class.forName(className);
Constructor<?> ctor = clazz.getConstructor(String.class);
Object object = ctor.newInstance(new Object[] { ctorArgument });

You might achieve something like using Java reflection

Class c - object.getClass();

object.getClass().getConstructors()[0].newInstance(initargs);
