Question

Look at this line below:

targetClass = Class.forName(className).newInstance().getClass();

My question here is why does he call newInstance().getClass();

Would it be enough to write

targetClass = Class.forName(className);

?

Answer 1

There is no sense to call newInstance().getClass(), because it will yield the same Class instance where it was instantiated from.

Rather, it creates an extra instance, that will be “dropped” immediately. Even it will not work, if the class does not have a default constructor.

Also, the cost of the instantiation, initialisation, etc. may be remarkable.
