Reflection and annotation that doesn't define

Question

I have programmed an app that gets name of an entity class and based on it, makes a UI. For doing so I created a few annotations and used them for the entity fields. One of these annotations is @Label that holds the name field and others are @IntType , @StringType ,... that hold the field types.

I want to know, if I write an entity for creating a UI that doesn't have one or both of the annotations, how do I handle these exception? Just with a try/catch block?

Answer 1

You can make a custom exception like AnotationNotFoundException , and throw it where you control the anotations of entity. Then catch it in your main method of app. You can log it somewhere like ui or log files.
