class.forname() is used to create an instance of a class on
the basis of the name in string format instead of doing new
Class. One of its use is in cases where you have some
generic (common) logic to call methods of some classes just
on the basis of the names of the class and the method. The
example of reflection shown below uses the logic.

Eg:
performAction(String className, String methodName) {
Class class = Class.forName(className);
MethodUtils.invokeMethod(class.newInstance, methodName,
null);
}
