thank suggestion

sonar has quite explanation of examples

according joshua bloch, author of "effective java":

the constant interface pattern poor use of interfaces.

that class uses constants internally implementation detail. implementing constant interface causes implementation detail leak class's exported api. of no consequence users of class class implements constant interface. in fact, may confuse them. worse, represents commitment: if in future release class modified no longer needs use constants, still must implement interface ensure binary compatibility. if nonfinal class implements constant interface, of subclasses have namespaces polluted constants in interface.
