I am building an application for a client and I am in the situation where I need to have the ability to reference a field value via a string, i.e the users uses a string to define which field they want to change the value of, this is part of an abstract framework so technically I don't know the name of the fields they desire to change. Of course I could do this using hash maps, but I am considering using java reflection as this allows the fields to stay as fields of the object rather than the values being coded into a hash map. I have used reflection for my own personal work, but I was wondering if using Java reflection is actually bad practice, and I should stick to the hashmap methodology.
(Any other suggestions for solving the design problem described are also appreciated)
Thanks
The question itself is opinion based, although I believe most will agree that you can't just say "reflection is bad". Sometimes it's the only way, which is why a lot of libraries use reflection. Sometimes it's not the only way, but a workaround would be even worse. Sometimes it's not the only way, and not the easiest way, but the developer is far too amazed at the power of reflection to think straight.
Except for that last one there are plenty of valid reasons to consider reflection as a solution.
