You don't have to provide a zero-argument constructor, but you do need to make sure one exists. For example, if there are other constructors then there is no implicit zero-argument constructor. The easiest way to make sure one exists is to write it yourself.

Thank you DrClap for your reply. I have on more clarification, is providing getters and setters not a mandatory requirement for a java bean

Well, I don't want to speak for your unnamed source so I will leave them to speak for themselves.
