Your question might be way easier to answer if you specify (a) what your actual task is, and (b) what your "helper class" is supposed to do ... in general, you can create as many different classes as you like, for whatever purpose you like.

Helper classes are just a term that developers give to classes that are used to assist in providing some functionality, though that functionality isn't the main goal of the application.

A Helper class is a simple java class. It is used to reduce the amount of redundancy in your code. Basically, they are utility classes that may be used several times accross the application.

Yes. Indeed you can, but, the precise thing is that making a helper class just for the sake of separating a customised task may not be the best option, if it's just used at a single place.
