It is not. Java dinamic as runtime (if that means something) but is statically typed. Java is dinamic in some ways, arrays have not declared size, has reflection and dinamic method dispatch, but all clasess and are declared and required. A final class can be represented as a simple (plain) struct if the scape analysis tells so, and allocated on the stack. Else, that inmutable object can be used as a lock, inserted into a collection (think hash) or whatever you can do with an object.
