I recently studied the concept of reflections in java, but I am unable to find the practical use of it?
Can anyone give a practical example where some problem can be solved only by reflection or reflection is the best way to sole that problem.
Reflection is widely used, and dependency-injection is one of the examples.
You can describe concrete class name in your configuration file and then create an instance of the class at runtime by reflection.
