I've used more Java enterprise frameworks than you can shake a stick at; I started with Java 1.4 mostly so I'm certainly aware of those patterns! Whether they are "equivalent" depends on your definition of equivalency. Could Java pre-SAM claim to have first-class functions; I would argue not because there was a separation between methods and classes - even though you could make a case that by having `Callable` or whatever anonymous classes you could use to emulate similar behaviours. Does Haskell have inheritance? No, but you can emulate some parts of it with a mixture of template haskell, record types and lenses.
