How can i define multiple constructors and states using gen-class in clojure? I do not see a way to do this with single valued mappings for :init, :state and :constructors.

Multiple Constructors
To have multiple constructors on the generated class you need all the constructor parameters specified in the :constructors option of gen-class, and the :init function should be multi-arity to match. Something like the following:
In this case, both constructors would call the same zero-parameter super-type constructor, as specified by the empty vector values in the :constructor hash-map.
Multiple States
State is generally a hash-map, so you don't need multiple states. Just use keywords where you would use field names in an object.
