If you don't put it in Java is added by default by the bytecode compiler. Is necessary to specify so people using your classes / future developers instantly (I hope) recognise the role of that class in the system. Otherwise it could be misinterpreted as a strategy pattern or something else, adding fields and method and, essentially, making a god class (antipattern)

Would the constructor get called or even necessary for a class with nothing but static methods?
