Adding new way of creating through factories.

Other uses you may think of is with DocumentBuilderFactory when working with XML in Java. A factory helps to hide implementation details from public interfaces and support polymorphism as you only need to know the kinds of behaviours that the object created by the factory adheres to and not how the factory creates it.

2 and 5 above are same.
this.getClass().getClassLoader().loadClass( com.amar.myobject ).newInstance();
is same as
Class.forName(com.amar.myobject)

And important point about clone() method is that, it would only work for those classes which implement the Cloneable interface.

Not one of those examples will compile. Interesting and informative topic, but syntax is important!
