Dynamic Loading vs Static Class Loading in java

Class in java can be loaded in two ways

Static means at compile time means using new operator.

Dynamic means using class.forname() a class is loaded dynamically during run time

so a decision to load a class dynamically at run time can be taken based on certain logic using property file etc.

getClass(); getName(); getDeclaredFields();
Instance can also be created using forName() method. It loads the class into the current class memory.  

it is similar like Reflection.
