    @irene i am writing a framework in java and it just makes everything so easy to work with. It's not pretty but it does the job of hiding the complexity from the user.

    An old professor of mine once said "If you need reflection, you're doing it wrong."

    I'm inclined to agree in all but a few specialist cases tbh.

    @irene oh it's definitely hacky way of doing stuff. But when writing a framework using reflection can make the code actually a lot cleaner but at the cost of making it confusing.

    @gvnix What framework are you writing? That's almost never the case in my experience.

    @AlmondSauce So its an old application based on swing, I was writing a custom UI framework based on graphs. We can create a BaseUIPanel which may contain various UI elements.

    Now to decouple actual code from listeners attached to these components I wrote another interface IActionTask which actually does the job but this has BaseUIPanel (an interface) as a param, so in this task, we cant extract any value from the UI elements.

    To remedy this (and avoid bad casting), I wrote a method that takes the obj, and field name and returns the object.
