no, not through reflection.

reflection asks classes , members, can change fields cannot create new ones. cannot add new methods.

you can use a bytecode manipulation library add methods classes; why want to?

you can't call methods anyway except via reflection not exist @ compile time.

maybe take @ project lombok - annotation preprocessor can add methods classes @ compile time. add getters , setters automagically long classes correctly annotated.
